Yep, 12 gallons before I discovered my error. Now what.
Didn't start it, had it towed home.
Just for grins and giggle, looking at sub zero weather in a day or so.

You could remove the fuel line from the LP, or similar location, and drain the fuel as it gravity feeds into a few 5 gallon pails.
Once most of the fuel tank is drained from the tank, re-hook up the fuel line, fill the tank with fresh diesel and add some 2 stroke to help lube things up. Prime the fuel system and fire it up.
Then stop adding gas to the fuel tank.

So where was that nag when I needed him?

I figured I'd take the fuel line off at the lift pump and adapt it to a hose...to a pump, and pump it out.

I was hoping I could add enough lube to run it without hurting anything.

oliver foster

If you can get the fuel hose lower than the tank it will drain itself without a pump.
It might be easiest to attach an added length of hose and use a barbed adapter to get it into a 5 gallon pail or the like.

12 gallons of gas in a 35 gallon tank is a little strong of a ratio for me to be comfortable with adding some lube and just running it.

Just think of all the bonfire starter you will have though when your done.

I'd disconnect the grid heater. Just to be safe

If the truck wasn't started then zero gasoline got into anything but the tank. Just drain it, refuel with diesel and motor on.

Drop the tank... And thank Edwin for his insight.

I realize that it was not started so there is no gas in the lines or the injection pump.
I just feel that pulling a fuel line and letting it gravity feed out sounds a LOT easier than dropping a half full, or worse, tank and re installing it in the sub zero cold.
He doesn't need to get it 100% empty, as a little gas in the diesel fuel with some extra 2 stroke oil added will be fine.

Personally, I'd add a gallon or two of lube/cetane booster and roll with it.

Our old deuce and half with a Continental diesel says that 50 gallons of gas with a gallon of engine oil is a fine substitute for diesel.

From experience, these engines run fine on 50/50 gasoline and hydraulic oil.

Just for information, setting aside damage to the injectors and the inj. pump, will the Cummins engine even run on gasoline? I've heard that because of the anti-knock compounds in gasoline that the engine will not run under compression ignition.

Yes. I agree that letting the tank drain from gravity and or even siphoning out the fuel from the fill tube would probably be easiest The problem is how much fuel would be left. If it were a gallon or more I'd say it's better to not take the chance of damaging something.

Couldn't a drain plug be fitted into the tank?

I have to agree with the others.....drain the tank as best you can, it's already a 50/50-sih mix of gas and diesel. Probably do the gravity from the fuel line first, then once that stops flowing try and siphon through the filler next. Once you've gotten out all you can fill it up with fresh diesel, some engine oil or 2 stroke and get rolling.

Had a buddy who had the opposite years ago to his 79 Chevy pick up.....some young lad at his work filled it with diesel. It was a dual tank truck so he ran the other tank to about half, then drained about half the diesel into the other tank, then topped up the tank with gas. Ran like garbage for a couple weeks.....but he did eventually burn through it.

Years ago some senile old pump monkey filled my '95 CTD about half full of gasoline before I realized what he was doing and stopped him. He said I TOLD him to put gas in it. I said that was funny since I parked in front of the diesel pump and he had to stretch the gas nozzle to reach the truck. The manager (Senior Pump Monkey??) came out and said "just dump some motor oil in and drive it. It'll be fine." I told him in no uncertain terms that wasn't going to happen. After some angry conversation I started it up and drove it literally across the street (engine running for about a minute) to a garage who drained the tank via the fuel line coming into the LP. After some more angry conversation they paid the garage and a gave me a full tank of fuel (that I pumped) for my trouble. The fact that I was on my way to work and was late helped me out a bit.

The roll over valve in the filler neck does not allow you to install a hose to siphon anything from the tank. I would also pull the line off the inlet of the lift pump and lower it into some 5 gallon buckets. If your wanting it to drain faster apply a few pounds of air to the filler neck. Once you have it drained in that manor I would fill it with diesel and some stanadyne diesel additive. In 3 more days it's going to be cold enough you'll be more worried about gelling up than the 2% gasoline you have in your tank.

NJTman

I just thought of an easier way of doing this.

Don't remove anything, other than the filler neck tube. 3 little screws, one hose clamp, and you have instant access to the tank for siphoning.
