Archived 7 Gallon of Gas in the 35 Gallon Diesel Tank

[REdmon]

Wife just put 7 gallon of Gas in a 35 gallon Diesel tank. I will drain the tank (Tried to siphon) but can't get a line all the way doen into the tank. Is there a screen or filter to block getting all the way down. If so, do you have to drop the tank to drain. All help is appreciated. Unhappy guy!

R, if I were dealing with this, I'd pull the filler hose from the tank, then siphon all the fuel out I could, refill with diesel and motor on.



Don't be to hard on her, it's happened to a lot of guys.



Good luck, RJR

If on level ground, jack back of truck up place on stands or back up ramps. Disconnect inlet to LP and drain away. If not able to drain, connect 3/8 hose to inlet of LP, get end of hose lower than lowest point of the tank and get a syphon going then drain er down.

A buddy of mine pumped 5 galllons of gas into his truck before he realized he had the wrong nozzel. The shop he called towed it in. This truck is an 05/3500. I went by the shop the next day and the tech had hooked a hose to drain valve on the filter body and hot wired the lift pump at the fuse box. Took a little while, but pumped it out and we poured in 5 gallons of diesel and was off and running. I told him to blame his wife also but he insisted on stepping up to the plate.

I don't think you have to drop the tank. If it is anything like my 95, there is a block at the end of the filler tube that you need to get past. Probably by removing the tube.

I think it is something they use to keep from spilling fuel in case of a roll 0ver.

a gas station jocky put 5 gallons of regulas in my tank before he noticed that i had a diesel . i had the choice of 5 hr layover to get the ram drained and as the ram was close to empty ,i told him to fill her up . that took another 25 gallons of diesel. i was on vacation so i took the risk,drove it on the freeway at 55 60 mph for the next 8hrs and had no problems i guess i was lucky or maby it didn't make a big differance. the 99 3500 has 99,000 miles onit and has never failed me EVER

And this is your first post... welcome to TDR!



Get out of the tank what you can using one of the above methods. You DO NOT have to get out the last drop! Add a gallon of decent quality engine drain oil to the tank (or the cheapest new oil you can find). Fill it with diesel. You should be fine.



Though not recommended, you can in an emergency add up to 10% gasoline to diesel to prevent gelling in cold weather. I have run my truck on a mixture of 1 gallon gasoline and 1 quart motor oil a few times to get to a station where I could fill with diesel. Unlike some would have you believe, a little gasoline will not ruin a diesel! I add a gallon of used motor oil to my fuel every fill... and have been doing so for 450,000 miles. The oil won't hurt a thing and will help restore lubrication lost to the gasoline.

See the post above mine? Another option would be to just add 2-3 gallons of oil and fill it with diesel and not worry about it!

If you can, grab a container of Power Service or some type of Cetane improver to help make up for the drop caused by the gas... you probably won't need the anti-gel stuff this time around!!! :-laf

When I was trucking, some guys would add 10% gasoline to their tanks at every fillup as a "winter fuel". I never did this.

I'd get a gallon of two stroke oil, pour it in, and top it off with the right fuel.

I have a 12 valve engine. The newer ones are a bit more finicky with the fuels.

When I hauled gasoline, we would add gasoline to our fuel to stop gelling. Sometimes we added JP-4 to to fuel. As long as you have something to increase lubricity for the pump, it should be fine.

The restriction in the fill hose is a ball check valve. It's in the plastic tube part of the fill line. If you remove the hose @ the tank you'll be past the obstruction.

 

[Dean Thomas]

The restriction in the fill neck is a roll over valve. It prevents spillage in the event of a roll over. I've had to syphon gasoline out on two occasions and one or two 1/2" o. d. hoses will snake through the roll over valve at the same time. Syphoning it out is not a speedy process but it will drain it down to 1/16 of a tank or so. Fill it back up with diesel and you are on your way.

Thanks for all the useful information. I knew joining TDR would be a great resource from the time I bought my 99' 2500 Dodge cummins. All the best everyone.



Thanks,

?

So Ron what did you deside to do?

1. just run it out.

2. drain it out.

3. add something and run it out.



Just curious

Put some two stroke oil in the tank and you should be ok.

My second hand experience

A friend of mine who tows a heavy RV put 12. 7 gallons of gas in his 03. At a truckers recommendation he added a quart of 10 weight oil to the tank and just drove it out. I'm not recommending this to you but so far his truck has been fine. Ken Irwin

I decided to drain the tank, refill with diesel, add a quart of ATF, and so far no problems. Thanks for all the suggestions.

For me it would depend on what truck I had. A 3rd Gen or 24-valve with 7 gallons I would drain most of it and refill adding some lube oil. On this old '96 I'd throw 3-4 quarts of oil in and burn it off, keeping an eye on the pyro and not running it hard.

I did this same thing with a Duramax I had. I put half a tank of gas in it while half asleep, ran it about 15 miles pulling a big farm tractor, realized what I had done, pulled over, drained it with a siphon hose, added 1 quart of ATF, filled it with diesel, started it, and never had another problem with that truck. I pulled this boneheaded stunt when it was fairly new.



You should be fine unless the Duramax is just a tougher engine than these Cummins .
