I have a diesel tank (Filled with Off-road diesel) mounted in my bed under the toolbox for filling up my mowers and tractors and equipment and I was wondering if I put a dump off valve in it so that I could dump it into my fuel tank if the higher sulfur died diesel would harm my fuel system??

Tax free diesel would save a good deal of money seeing as I run three to four tanks a week

Use of Red Diesel Fuel in 6.5L or 6.6L Diesel Engines - kw hard INJ INT LB7 LLY L49 L56 L57 L65 miss P3 pump stall start #PIP3207 - (Oct 28, 2004)

The Use of Red Diesel Fuel in 6.5L or 6.6L Diesel Engines.

.

The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.

Condition/Concern:

Dealer notices red diesel fuel being used in vehicles equipped with a GM 6.5L or 6.6L diesel engine.

Recommendation/Instructions:

Red diesel fuel will not cause any problems when used in the fuel system of vehicles equipped with the GM 6.5L or 6.6L Diesel engine. Red fuel will not induce trouble codes. Accordingly, warranty decisions should not be based on the discovery of red fuel in the fuel system or the injection pump of a GM 6.5L or 6.6L diesel engine.

Federal regulations require certain diesel fuels be colored with dye for tax purposes. Diesel fuel injection pumps have been tested with various dyed fuels and have been found to operate satisfactorily with such fuels. Water or other fuel contamination is not covered under the Stanadyne and Bosch warranty regardless of whether the fuel is dyed or not. All GM vehicle owners manuals state to use a #2 diesel fuel. A change is being made to the service policies and procedures manual, section 4.6.6 to reflect this information. With regards to legality if a customer requests to know what fuel is legal for them to use, refer them to their local government agency for handling. Please refer all inquiries to this document.

.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance.

Depends on wether or not you want to risk a very large fine if you are caught. In ca, the fine is $10,000, and an instant audit.

From a mechanical standpoint, there should be nothing wrong with running Red in your truck. I am almost sure that it would have the same amount of sulfur as regular diesel. In my experiences, the only difference is the dye.

My luck Id add the fuel, and then get dipped.

BTW, they are wise to adding the line from bed tank to truck tank. In fact, they may be more likley to check you if they saw that.

MannyTranny is 100% correct. I know of a person that got hit with that fine. Several months later they did a random check and caught him again. You will not save a dime over the long run. I doubt that he saved $20,000 in road taxes.

How big of a chance are you takin? Around here Ive never heard of anybody actually being checked

The problem comes if the truck is commercial. If the State DOT pulls you over and inspects and finds it, you are in a lot of trouble. For people who do not have their truck registered commercial.. the chances of getting pulled over for fuel are slim...

The chances may be slim, but a $10,000 tank of fuel seems pretty expensive to me just my .02

I live in Guntersville, AL I have never seen or heard of any one getting checked for red fuel around here. Population 7,000 I dont think they check that kinda thing around here that is why I was considering this a solution to high cost fuel.

I have been running dyed fuel in my mowers and skid-steer Bobcat. I cant get fined for that can I??

The Tennessee law is basically anything that has a license plate or has the ability to be registered for on road use can't have red fuel...this is regardless of whether the vehicle is actually licensed or registered for onroad use. For example, if you have a truck that doesn't have a license plate, is run only on the farm can still "technically" get a fine.

And as far as the chances being slim if you are not commercial....well, Tennessee conducts random roadblocks are just as likely to catch a yuppie in his diesel pickup on the way to the grocery store as some commercially-tagged vehicle.

Same here in AZ. and they do perform random road stops just for pickups. The DPS (Highway Patrol) as a routine dip/check tanks when stopped for any violation. It is also a $10,000 fine here and I actually know some folks that have been caught and convicted. If you can afford a truck like this, you can afford to buy the fuel. "Don't be stupid".

i run it in mine every once and a while. dealer said it wont hurt anything

The red coloring stays in the tank for MANY tanks after the first fill-up of off-road diesel. Just a warning, it's your nickle.

A local diesel guy around here, told me that running the high-sulfur would help out my old 6.2 in my blazer. Something about a flash burn that helps keep it clean. Thats just what he said. I'd agree with most everybody though that 10k a tank is pretty pricy. You may or may not ever get though, but you will sweat like a stuck pig anytime you a see cop.

I've heard stories of local farmers getting busted at auctions etc for running off road only diesel. But then again more power to ya if you get away with it):h

According to the California Vehicle Code the only penalty for getting caught using Red Dye Tax exempt fuel is a fine. $10.00 per gallon.

I would think that someone who runs the Red Dye fuel on the road is the same kind of someone who removes the catalytic converter and blocks the EGR. I would think there is a pretty good potential for that guy to get fined heavily, maybe even serve some time...fooling with emission systems and all.

I'm not expert but if it's as dumb as it sounds I pray that he gets caught and thrown in jail before he reproduces to do the gene pool a favor.:joke:

One of my employees just got caught running dyed fuel in his own pickup 2 weeks ago. The next day I was visited by an IRS agent to audit my fuel buying procedures. I provide his fuel and he is supposed to fill at a station but he was in a hurry and fueled from my red dyed tank. I'm OK, it's his problem but the IRS agent told me that the minimum fine is $1,000 for the IRS and $1,000 for the state. If you have over 100 gallons then the fine is per gallon, the amount to be determined by the IRS. So if the vehicle code says $10 per gallon that will be the least of your problems. He was stopped in a checkpoint in Cental California.

I chances of you locally getting checked for diesel running around your home town are slim to none. But it you run the highway a lot I think you stand a good chance of getting checked. If I was smarter in chemistry i would find a way to remove the red die from the fuel. because i think the gov is getting too soo much money now that they will never be able to run a surplus budget.

i say take the car/mini van on trips run road fuel when pulling the 5th wheel.

when my cousin went to canada he got stoped at the border for the fuel tank in the back of his truck. they said if it was taped to the fuel tank on the truck he would never been bothered. but the US doesn't want you to do that.

btw he was running road fuel so no fine. but i really don't believe they can tell the traces I will say that. :p:

I would say if you want to tap into the fuel tank . go for it. make the line discrete with a small whole in the corner of the bed. then make second spot for the OEM looking fill up spot and put road fuel in there. so if you get tested they will see road fuel. :)

Well it has been done. I put the tank on my trailor and fill it up at the station and then when the Max gets a lil low I put a lil red fuel in her.

I never run the HW takes too long (Traffic) the back roads are much faaster and safer.

how about this idea, run a line from the cell in your bed to the filter or wherever in addition to the line from factory tank, have a discreet electronic switch some where in cab and always keep at least a quarter tank in factory tank, so if you do get stopped, flip the switch and run the road fuel incase they check you filter...what do you think about that idea?

):h Better yet... Anything out there to "bleach" out the red dye?

The people that check the for dyed fuel are trained to look for fuel lines and such, especially when they spot an aftermarket fuel tank.

A good friend works for the Motor Carrier Division of the state police. He told me they dont need to test the fuel, they can pick it up in the exhaust. He also told me he has NEVER checked a stock pickup for fuel issues. unless they are hauling diesel equipment and they are stopping them for equipment inspection, or they are plated commercial. He also said they rarley stop a commercial plated pickup, gas or diesel unless it is moving equipment or loaded with materials.

He said they are way to busy dealing with the large GVWR trucks and have little time to mess with the pickups.

about 5 years ago I saw a 'diesel vehicle checkpoint' setup in downtown pittsburgh. They had a sign in the middle of the road 'all diesel vehicles must stop here--->' and they were dipping tanks. This was before exhaust sniffers and before I owned a diesel, so it didn't affect me and I didn't think anything of it at the time. Haven't seen anything like it since. Just thought I would pass it along.

How can they tell from the exhaust??? Would it be the chemicals released from burning the red dye??

They might be able to see a higher SO2/CO2 ratio coming from the higher sulfur.

what higher sulfer? red dyed fuel is #2 but with a dye in it and you don' t pay the road tax on it.

As of yet, off-road diesel has no upper limit on sulfur content. Without treatment sulfur in diesel can be as high as 10000 ppm. For onroad the federal limit is 500 ppm. In cali it's more like 30 ppm.

Off-road will get a limit soon though.

some stations in california already have 15 ppm diesel

HMMMM, the fuel supplier that we buy fuel from at our concrete plant told me that there is no difference between the two. And he is the manager of the place. He must not know what he is talking about.:rippedhan

maybe you could mix it with blue and green food coloring til you get it back to green!! :badidea: J/K for anyone who actually might try it! I read a couple reports and it looks like we better get ready to pay an additional $ .25-.35 a gallon by summer time -:t . I vote to nuke china so there will be plenty of fuel for us

Seems that crude availability is not the problem. More like the Futures market is driving up the cost more than global demand. That and the low volume from the domestic refineries. Get more refineries online and find a way to curb the futures buyers from buying up prices and you'd knock the price right down.
