So I finally had a reason to use my TFI big fill neck this past weekend. What a true pleasure.


So I come pulling into the huge gas station off the 99 only to find a sea of cars, trucks with various trailers and motorhomes with cars in tow. The general consumer filling part of the station had cars backed up out onto the road...It was sheer chaos. So I went around back with my boat in tow to the tractor filling bays. 26 drive thru bays. only about 8 tractors. I drove right up and hopped out. I was between a few tractor trailer rigs being fueled. One of the guys said "Hey just so you know, you cannot fill fuel from here into your truck, the nozzle is to large" I said "I had it modified" he did not believe me. So I proceeded to swipe the card, dropped in the nozzle and BOY HOWDY does that pump move fuel. The counter for Gallons was clicking off lighning fast. Needless to say I filled my truck in less than 2 minutes including topping off as I always do, 41 gallons. I was in and out of there like a NASCAR pitstop and what was extremely nice was their is 1 pump per bay so nobody pulling in the wrong way or blocking up throughway with another trailer or having to wait for someone who has not got in tune with using a CC card for fuel.


For anyone considering this nozzle upgrade I highly recommend it. It made my traveling this crazy 4th of July weekend and cake walk.

How much of that tank do you actually find useable?

Well TFI has stated 56 Gallons. I have put almost 60 in it. My low light comes on and that leaves me a reserve of appx 7 gallons (Based on fill up after light came on). Of that maybe 4 more can be used. But that would have to be level ground or going up hill. I know pointing down the pick up may not see fuel depending on angle.

Is your tank in your bed, or did you remove your spare?


Cost for parts and installation?


I'm right in San Jose, too, so I'd appreciate some feedback. This is something I've been wanting to do. You can PM me if you want.

This is the first diesel ive had so im not sure about the different sized nozzles...The other day I was filling up where I usually fill up and a guy with a 02 3/4 ton duramax on the other side of the pump asked me if i had already punched out the hole out or if it came like that, I guess mine just came like that I dont know, is there only two different sizes of nozzles? does this mean I can fill up off the pumps the truckers use?

I didn't get the replacement tank but I did install the TFI fast fill neck kit last week. It takes longer to find the bottle of fuel additive, remove the foil and remove the locking cap than it does to fuel up. All the frustration of fueling up is gone. No foaming and the pump doesn't click off every few seconds. It's well worth the money.http://www.dieselplace.com/forum/smileys/Big Smile.gif

I would like to see the TFI fast fill neck if possible......anyone want to take a picture ot 2 of it laying on the ground or even installed???

Me too in real life ....

I have been looking at these tanks for a while, but man are they spendy.


By the way, what kind of boat do you have?

Lightning,


Well you know I agree the price seems high but when you go on an entire trip and you do not have to pull in for gas it is money well spent. I think the larger importance to me is getting good fuel all the time. I can fill up here at my known good stations and not worry about having to pull off at some station that who knows how long the fuel has sat....


I have a 2004(bought late in 2003) Sanger V210 Wakeboard series boat.


As for the picture requested above about the fill neck, it looks identical to the factory neck, same bends It simply is a bit larger in diameter and the opening will accommodate the LARGER fill nozzle found at truck stops. It is amazing how fast it fills and with no foaming.Edited by: Duramax Dually

My 04 has the larger fill hole and I pulled up to the BIG pumps one time because the small diesel pumps were in use, the attendent looked at me like I was an idiot, but man o man I filled up pretty quick!


I'll use them again just because its so fast


Rob

I too am very interested in both larger fill neck and larger tank.


I have an 04 LB7 built in Oct but it still has the smaller neck. The new trucks seem to have the larger neck. Would it be cheaper just to get the new fill neck from GM--the one for the new trucks--than the TFI fill neck kit? I am wondering if there any issues using in on the older trucks?


Since I am also looking at Supertanks--they do not yet have a larger fill neck. But a larger OEM fill neck(for the LB7 guys) with the supertank fuel might get both the bigger tank and fill neck.

It's easy to get the big nozzle to fit ,it's the venting that gets the shoes wet .... http://www.dieselplace.com/forum/smileys/Angry.gif



I'm gonna order one,a fill neck and it better work or I'm gonna rant ...





Mac http://www.dieselplace.com/forum/smileys/Geek.gif

I know--whats worse--while down in Mexico(large pumps only)--they pump the fuel--all over the side of the truck--the truck was dirty due to off roading--what a mess.


Mack--are you going to buy the GM fill neck for the new trucks or the kit from TF?

The fillneck off of the new trucks, will not work on the LB7 tanks. They are vented different. The fillneck off of a new tank would probably work if you were to make a section out of pipe that fits in the hose going down to the tank and putting a hose from it to the new fuel filler neck for venting. I would imagine it wouldn't be hard to build. As of today, when I called Transferflow, they didn't have any in stock as I was going to buy 3 of them. I just ordered 9 tanks from them, and the only ones ready were the CC short bed LLY tanks. The rest have a production date of July 19th. tpitt

Hmmm, the SuperTank has the internal vent and also an external vent (new update). I wonder if that would allow it to work with the LLY filler tube? Anyone know? How much are they and anyone got a part number?

I should call Supertanks and ask if the tank they make for the trucks will work with the LLY fill tube.


tpitt: assuming the supertank does work with the LLY fill tube--can the LLY fill tube be attached properly on the LB7 trucks?

I will be on the list for a TFI neck ....





Mac

One word of caution for you guys with the LLY fill tubes. When I was getting ready to leave on our trip for Texas, a guy with a new LLY pulled up to the other side of the pump from me. I was using the small nozzle so he had to use the big one. I know he had the new LLY because he stuck the whole nozzle in, I have to hold that one in place the whole time.


Any way, he proceeded to fill his tank in record time. The pump clicked off, he pulled the nozzle out and at least a gallon of diesel if not more spewed out the tank.

RonJT,


I haven't personally changed any LLY tanks yet, but I am sure the filler necks will bolt right in. I may be changing one next Tuesday. Aren't the Supertanks more expensive than the Transferflow? I sell Transferflow tanks and other products. Guess its time to check with Nick about advertising. The reason I haven't checked before is that I work fulltime as an Equipment operater for the California Dept of Forestry and never know where I'm going to be in the summertime. tpitt

Here are some photos of the fill neck kit after installation. As someone posted in another thread, what you actually get is different than what they show in the pictures of their website.


I've filled up a few time since the install and haven't had any problems. The pump clicks off when its full without spilling. The instructions are very clear regarding the installation of the new vent. It must have a downward slope and must not create a P-trap. The same goes for the fill line. You don't get enough vent hose to create a p-trap so that shouldn't be a problem.

Not enuff profit marging on this item for a group purchase? @ $127 one would think so but in todays world who knows?

DuraBull,


Thanks....just what I was looking for.....how about one more though, of the piece that is added in to the fill hose.....just before the tank. A look through the wheel house opening might get it on a short bed. Thanks again.


George

ShumDit,


Unfortunately there is not a lot of profit margin on Transferflow products. I have to buy $5000 worth at a time, each and everytime to get a better break. I just ordered 9 tanks, and hopefully I have most of them sold. This is the first time I've bought such a large amount, and as a part time business this is scarey. I don't have the cash flow to do this everytime. I'm in communication with Nick on this site to possibly becoming an advertiser here. tpitt

OK, I've got a dummy question:


I've got a 2004 LB7 in which the large fuel nozzle will fit, but as I think Mackin said above, it's the vent that screws me. I can fuel up at the big islands, but I have to sit there and babysit the pump. I can only run the big nozzles at about 50% on the handle or the overflow kicks off.


Is there a kit / method for merely improving the vent on our OEM 2004 LB7 filler necks?


(see? Told you it was a dumb Q)

Exactly CStone ....


The vent is poor to say the least in the stock fill neck .... I altered mine to except the larger nozzle ,you should see that one puke ...


My 98 and 93 6.5's stock fill necks worked exceptionally well ...


So I ordered the TFI and will give it a try for my Max I'm sick of the trickle fills ...


Very good Q ....





Mac

tpitt ~ yes, thanks for putting it into perspective. I'm about 40mins away but still sattled w/sales tax and unfortunately, they seem to be 'the only show in town' for fill necks. Where's the competition? Or even the DIY creativeness of our members?


Never had a big nozzle issue w/my 02 but foaming/puking and in particular the warm Guiness beer delayed eruption is taxing my patience. So, for me ~ its a vent issue rather than a function issue. Perhaps that what I should be looking at?

Big Dipper,


Heres two more shots of the new section before the tank inlet.

The metal vent pipe to the side continues to the inside of the fill pipe. Attached to that is rigid rubber hose that extends into the tank and completes the venting.


Install was easy. Hardest part was getting to the hose clamp connected to tank. Nictane made getting my arm up over the frame a bit tight but it doesn't interfere with the final setup.

Thanks.......


5/8 hose?


Edited by: BIG DIPPER

Yep,


5/8 i.d. hose it is.

I'm liking this more and more. The "SuperTank" has 3 separate vent holes in the tank. Two that connect to vent the front "pod" into the main "pod", and another that (as shipped) is plugged off in the tower of the main pod (air chamber above the pickup/sender). The "improved vent kit" I received on Monday replaces the plug with a nipple, and connects to the top of the filler hose for improved venting for faster fillups. You could coneivably build a header connecting all 3 of these (each is roughly 3/8" IIRC) to a larger 5/8 or 3/4" header. This should net a better vent rate than the 5/8" hose used by TF. Connect this into the LLY filler top cap and you should be gold for filling with the big nozzel. http://www.dieselplace.com/forum/smileys/Clap.gif

Word of warning:


Some states tax "big nozzle" fuel different than small nozzle (commercial vs. passenger).

That's true. In the past, I've had to go inside to get a tax credit after pumping at a truck stop where the higher commercial tax was the default.


BTW, I would love to see a pick of the LLY fill neck and tube if anyone has one. Does it also have the long hose that goes to the bottom to reduce foaming?Edited by: BadDog

So nobody has price or part numbers on the large LLY fill neck?


Also, anyone got pics of the back side? What about the hose assembly that goes in the tank to reduce foaming? How does that compare to an LB7?

Man, I feel like I'm talking to myself... </v:stroke></v:f></v:f></v:f></v:f></v:f></v:f></v:f></v:f></v:f></v:f></v:f></v:f></v:ulas></v:path><o:lock aspectratio="t" v:ext="edit"></o:lock></v:shape></v:imagedata></v:shape>


Anyway, I decided to give it a go with my local (typically) less than helpful parts dept. The guy was actually helpful and seemed to be trying to help this time... But then I found out that they apparently only come in solid unobtanium with 24k gold plating. Just the filler head where the gas cap screws on; just that little metal thing at the top of the hose, bolted to the bed side; that little thing alone is over $300! </v:imagedata></v:shape> I asked if they came in only silver rather than gold plating and he just chuckled and said he didn't see a listing for that option. And the 2 hoses, over $80 each.


Those are round numbers as close as I can recall. When he gave me the prices my blood pressure skyrocketed and I seem to have had a mental failure...


So, I guess that idea is a bust unless someone has better connections or I find a 2004 LLY with damaged driver's bed side (but not too close to the filler) in a junk yard. I even called a local commercial bed shop that mounts the utility beds to see if they had a pull of bed I could get a filler neck from. Apparently they actually unbolt those and use them in the new beds. I figured they used a custom chassis cab like arrangement, but no joy there either…

They wont ship till End of July to August 1st or 2nd ...


So you'll just have to wait till I get mine for a pictorial and use results ...


On order ...





Mac

Sounds like a good upgrade option!http://www.dieselplace.com/forum/smileys/Clap.gif

Another possibility. Could an old 6.2/6.5 filler neck be grafted into the cup that mounts inside the bed side? It would need an external vent line, and something creative if you want to keep the line going to the bottom to reduce foaming, but it should work well on after market tanks with vent provisions.


Unfortunately, I hauled away my old 84 diesel tank and filler neck a few months ago along with a few dozen other things I wound up needing... If it works, I think it will be a much better design than the in-and-out vent of the TF option.

Mackin,


I just ordered a fill neck kit myself &amp; was quoted july 22 as a possible ship date so maby TF will get their shipment in a little early?


Also, I talked to one of the installers at TF &amp; he said that if you have any diesel pukeing issues, just rotate the hose somewhat &amp; that should fix the issues (i.e.: from the 2 o'clock to the 4 o'clock position). The guy said that we should not have ANY problems with filling our tanks &amp; he very rarely has to re-set a hose.


So . . . . we will see.

The sooner the better I need fuel ! But the Gent who called me to confirm my Faxed Order was pretty sure on the August date.


Lets hope a early delivery is in the works,shipping two days on my dime,make that a quarter.
