Gas in diesel

[AH64ID]

Any diesel specific lubricity additive is what I’d run. I personally run Amsoil when I want an additive, but they are all good.

Years ago I tried 2-stroke in my 05. It didn’t burn completely and left a residue in the exhaust and caused a sticky exhaust brake. CR’s are a more efficient burn than a VP, so I don’t ever recommend 2-stroke as it’s not designed to burn at the low temps that a low load diesel burns at.

Thanks for your help!!!

If that is not possible for what ever reason, I'd flush it twice. Syphoning it out, drop in 10 gallons of Diesel, syphoning these out again too and then fill it to the top after you have added a good additive like Power Service that is recommended from Cummins.

Sorry I was offline during the day.

That's what I'd do with my truck in your situation, Diesel is much much cheaper then the injection hardware. Don't gamble here.[/QUOTE]

Find out what to do with the contaminated Diesel before making more. In other words drop the tank! Adding Diesel just to flush it out is making more hazardous waste to deal with. It’s not easy to dispose of it in my area…

I'd spend it to someone that has a vehicle with a good old in-line pump that can burn it.
Farming- or Construction Equipment would be my choice.
Don't use it in a furnace or stove, it would blow up.

Drop the tank is best.

 

[William gran]

So appreciate all of the responses Looks like I’ll drop tank and clean. Any thoughts of the best way to clean tank??

 

[Ozymandias]

Drain it, take the fuel sending unit out, collect the rest of the fuel inside with rugs/paper towel.
Let it vent for several hours for last residues of gas to evaporate.
Use shop air to speed up the process of evaporation.
Keep ignition sources away.

Done that way you're perfectly safe to fire it up after fuel up.

Thank you very much!!

I had an associate fill our 2012 full of unleaded... key was cycled and it was driven from the station back to the shop... I chose to pull the bed off as it was a few bolts, and electrical connectors. Pumped out 30g of contaminated fuel (mostly gas) and wiped the tank with shop rags. Filled with fresh fuel, two new filters and it has been fine. Best way is get that tank clean and as much of the contaminated fuel out.

EDIT [I pulled the fuel pump module and siphoned from the large opening, then I could get my arm(s) in there to wipe it out clean]
Here it a link to that saga.

Ok well got tank out today. I am a senior 74 but I did succeed. Finally pulled driveshaft which gave me a bunch more access to the top of the tank. Crap while feeling around the top of the tank dummy pulled on return line and broke off the mounting. Crap. Oh well it is a 11 year old truck. Cleaned the tank. This morning I lowered the rear of the tank and jacked front of truck up. Got more gas diesel mix out but kept thinking pull the tank, I did. Once tank was out maybe a pint of mix. Could have taken a chance but didn’t. Currently having an adult beverage. Will get a new fuel damn but maybe not a bad expenditure in an 11 year old truck. Going back together, I am hoping goes smoothly. Thanks to everyone with their direction. The plastic connections on the fuel module are pathetic maybe like me lol

 

[Turbo Terry]

Sounds like you did good. Hope the going back in works well for you

I'm not sure about the 4th gens but on my third gen that was why I had to replace the fuel pump module, the return line cracked and was leaking, the fittings on the module are moulded in and it must be replaced as an assembly.

 

[William gran]

No leaks on mine. I reached and was feeling around top of the tank and pow the return line snapped off at the fitting. I was thinking in the night maybe I could repair. Getting module takes sometime. I live in the high desert mountains and plastic never last. Want do you want for $360 metal fittings. Lol

Well, I repaired one once with a AN bulkhead 90 deg fitting and the corresponding quick connect adaptor you can buy at any performance parts dealer, but it takes some time and you have to drill / modify the plastic housing, not a big deal for the return as it just dumps in the basket, but still work.

Thanks no one stocking unit in northern Nevada. Might give it a try

Sounds like you are on your way to a good repair. But just to clarify some of the other posts, the problem isn't just the lack of lubricity of gasoline, it is the auto-ignition temperature difference between gas and diesel. Gas has a higher auto-ignition point than diesel and results in a much longer ignition delay that is very detrimental to the engine mechanicals. Just adding oil or some other lubricity enhancer does nothing to offset the difference in auto-ignition temp. Not only will you ruin the injection system, you can cause bearing, and piston damage. So the best thing for even small amounts of gas in diesel is drain the tank, flush system if started, and add new diesel, period. Doing anything less on a newer diesel is just risking very expensive repairs.

I remember my 81 VW Diesel PU owners manual stated I could run a certain percentage gasoline in the winter.

Dropped tank cleaned thoroughly. As I mentioned I am a senior so I am old and slow. While removing tank I reached above feeling around and broke off return line nipple. After doing research of trying buy a new fuel pump sender module I was a bit depressed expensive. There are plenty of Chinese units out there but I didn’t want to end up replacing in a couple years. Yesterday I found a gentleman that replaced his ram tank for a larger and it came with a new fuel pump sender module. He sold me his used one off an 18 model for $75. Had to drive into Carson city about 100 mike round trip. Have tank in place and one breather line to install and can install bands and tank will be done. Driveshaft next. Have a new fuel filter should be ready to go. I do have a question about first start up. Do I just do same start up procedure after filter change?? So glad I dropped and cleaned tank

yep, cycle the key a couple times and good to go.

No Problem!

FWIW its a big job for any of us,.. I am only 50 and I would not look forward to / or relish doing it again. My friend wants to do another upgraded clutch on his 05 NV5600... I've done it twice and have the tools to do them but that doesn't make it fun.

Best of luck, should be fine from here on out.

Cheers, Brian
