Anyone having any problem getting the longer LLY fuel filter from GM? I asked a dealer for one yesterday, but he pulled out the LB7 filter (I had one left over from my last D/A left over to compare with). He said he'd just gotten in the shipment and that was what they sent.


Are the new filters the same GM part number or not? I know there was some discussion about this before, but I don't remember the outcome. Also, I bought the RACOR for my LB7 which was a direct clone since they made the OEM filter for GM - anyone know if they are offering the longer length filter under their name yet?

In a word NO. My local stealer is the same way. When he calls up a fuel filter for my LLY, he comes with the shorter stlye can. I also checked with Napa and local Wix dealer and they also have the shorter stlye.

Kinda dumb - GM comes up with a better idea, with presumably more media and filtration capability, and then doesn't take action to make it available to the customer as a replacement option within a reasonable timeframe...


Thanks for the reply

I talked to a tech at Racor when the LLY first came out and he told me the inside element in the longer filter was the same part that is used on the LB7 filter.


The only difference is the can is longer and he didn't know why,


He did say the only thing the new filter would do different is hold more fuel and cost more but, it is no better or worse.

John,


Thanks for the info - now I am more mystified than ever...

That's good to know. I've got one left over from my last D/A.

Just to clarify, are the part numbers you gave for the long LLY filter?

Just for info, the AC filter I had leftover for the LB7 is "TP1298" with a GM part number of 89016324. If it is true from a preceding post that the filter media is the same inside both cans, maybe the extra space is simply to physically hold more water? Beats me...

http://www.dieselplace.com/forum/uploads/27E_DSC01162one.jpgYes, The part# given IS the LLY (longer) fuel filter... The GM parts list also lists BOTH part #'s (LB7 & LLY)... Your dealers' parts guy just has to look for it............Triffid Edited by: Triffid

Triffid,


Thanks for the response - at least now I know what to go back to the dealer and ask for...since they didn't know.

I talked to Racor about the filter thing while asking questions about the pre-OEM kit. The engineer I talked to said the same thing John R has reported above. Same media, nipple size, thread cut, mating surface, the whole thing is the same except for being 3/4 inch longer.


I talked to OFI the other day and they called Racor as well. OFI still has no idea when the Racor branded filters or any other aftermarket branded filter will be available, and Racor couldn't tell them.


So if you want a spare filter and can't find the GM LLY number, just use the LB7 filter, that's what I got for a spare.

Zeeb,


Thanks for the update - I'll go back to the dealer and see if they can get the right filter. If I have a strong reason to change the fuel filter in the meantime, I'll use the old one as a spare. As to RACOR not having the new LLY filter available, ya' kinda' wonder since they are (or at least, were) making the LB7 OEM filter for GM. Still, if GM has the new filter on allocation, maybe all available RACOR production is going to GM at this point...

Interesting......If you LLY guys look in your owners manual it lists the fuel filter part number as #97256734 and when you cross reference that number to a NAPA or a Wix filter it gives you the shorter LB7 type filter.

GM Part# 97256734 has changed to Part# 89016324 which is the "short" LB7 fuel filter...


GM Part# 97363539 is the new part# for the "long" LLY fuel filter...


Hope this helps.............Triffid

That should wrap it up - I'll know what number to look for at the dealer...thanks.

LLY filters are going to be avail on my website, which is now open!

Plugged the numbers into www.GMpartsdirect.com (http://www.GMpartsdirect.com) and get a price of $14.02, cheaper? than the shorter LB7??? Doesn't make sense.

Anybody else confused?

Can anybody clarify?

size dont justify price.

Will the LLY filter work on the Dinosaur Duramax LB7??


I can't see why not if the wiring pigtail is long enough and compatible ... Right ??

Not sure what this means. I just want to know, what is the real part number for the new (longer) filter?

I've not looked at an LB7 up close and personal, but from what I understand there is a clearance problem if you try to use an LLY filter on the LB7 because it's about 3/4 inch longer. Is there that extra room for the filter on the LB7?


The LB7 filter will fit the LLY according to Racor, so that's what I got for an extra filter before the LLY filter was available.

If they didn't change the mount ,which I doubt they did ,3/4 inches is available...


Mac

The LLY filter is said to not fit the LB7 because it hits the valve cover, however, one could be industrious and just put some spacers under the mount and move it up.


Masterp2.... the LLY filter is 97363539


When the LB7 filters first come out, they were cheaper too. part no change and viola... more expensive. I wouldnt be suprised if the same happened with the LLY. However, its possible they may keep the price down to encourage more frequent changing.

THANK YOU!!!

Eric


That's interesting can you varify that the moved the filter mount away from the engine ??


Think of the possibilites ....


Mac

I just took a close look at the filter head and the mount that bolts to the engine. The filter head flange bolts to the mount flange with two small bolts. It would be a simple project to build and install a 3/16 or 1/4" spacer but why. Until someone proved the LLY filter is better, why bother? Install a good secondary/primary and never look back. Later! Frank

Frank, your right, its not a big deal just to unbolt the three bolts that hold the filter head to the valve cover, install spacers and longer bolts and your done.


Mac, I think the design difference of the valve covers alllows the filter to fit. My head is already spinning on possabilities. It would include a spacer kit and no longer carrying the LB7 element

I changed the LLY fuel filter today and cut open the old filter. 6300 miles.

I don't have an old LB7 filter to compare to, but I think the media is longer. If someone has a LB7 filter cut open we can compare the elements.

I measure 3.75 inches on the LB7 filter, using the same points of measurement as you show in the picture (bottom to top of filter element). I measure 2.25 inches of exposed filter media in the vertical dimension.


Looks like the media is 3/4 inches longer on the LLY filter?Edited by: OC_DMAX

I asked our parts man at the dealer and the lly is ship direct.as a tech I looked at the parts mgr. said "are we going to stock these or waite until we sell it and not have it".he gave me a blank stare we have them in stock he pull out the lb7 I said no thats the lb7 we meed lly.
"they have a new d/max"oh did not know. and we wounder why we have such a hard time gitting parts right.wounder if he knows the nova it long gone.

All this does seem to point out some GM failures in their communication process with their dealerships. If GM engineers redesigned the fuel filter for the LLY (and from the posts above, it is a true redesign), then that's the filter the dealership should provide to the customer. Since fuel filter replacement is a scheduled maintenance item, all dealerships should have this item in stock or on order. If they're providing the LB7 filter in lieu of the LLY filter, then they are negating the efforts of the GM engine design team. It probably isn't a serious problem to use the LB7 filter (although I'd want to see that in writing from GM before I did it), but why not have the correct filter available to the mechanic or the customer?


This is probably more a GM management failure than a dealership problem, but either one makes it the customer's problem... Best answer, do what I did and order from Eric. Great price, correct item, fast service. Why would I want to stand in line down at the Chevy parts department (and get blank stares) when I have a better and cheaper option available? Make up a bulk order from time to time on your standard maintenance items and put 'em on the garage shelf. You'll need it eventually - face it, you wouldn't be reading all this stuff if you weren't a bit of a maintenance freak anyhow...
