diesel in jerry cans?

[rovingowl]

sorry for the ignorance but i was wondering if regular red jerry cans can be used for diesel? i was thinking that they should be the same as the yellow cans unless there is a difference in the gasket. is it safe to use a can for diesel that previously held gas?

I do not believe you will have a problem with the cans gasket.

Yes, they should be painted yellow. My German UN cans have green paint and tags that you put the correct tag facing out. I have never had anyone ever say anything to me about the color. Maybe under the right conditions the law may say some thing to you about it. I would not worry about it. If it is not dripping or leaking they would never open it to check.

The only time I have been questioned about fuel cans is going into Mexico. You are not allowed to bring fuel into Mexico in cans.

not really worried about being questioned. and i would paint them or label them appropriately when carrying diesel. i just wasn't sure about using them for diesel after gasoline or if the gasket on the gas can was different from the diesel can. i thought i read the sceptor cans had different gasket for diesel and gas, and didn't know if wedco was the same.

I switch back and forth and have used my red wedco cans many times for diesel during extended trips and have yet to have a problem so you should be good to go.

I used to run cheapo red cans with diesel in them and two eventually leaked (the can itself, on the bottom) I carried them on my roof and could always tell they were leaking because the diesel would screw up my wipers. I lived in Vancouver where the rig was always wet anyway. I never had a yellow one leak.

I don't know for sure, but I think the red plastic cans are incompatible with long term diesel storage.

thanks for the info, turbo. i was told it should be ok, but looking for confirmation from another source.

THE FUELS ARE NOT COMPATIBLE! The gas will change the flashpoint in Diesel and your truck will not run.If you use the gas cans for Diesel clean it out very good and mark the cans. I would by the yellows my self so ther is no confusion.

[rovingowl]

brut4s- i'm completely aware that the fuels are not compatible. what method would you recommend for cleaning the cans before using for diesel.

my current set-up is gas, but in the future would like to get a diesel. i was checking for future reference that it is possible to use the red cans for diesel. i of course would repaint them at that point.

Actually a small amount of gasoline(<10%) will have no effect on a diesel except lowering the flash point of the fuel which is a consideration in an accident but not for the running of the motor. I ran ~30% gasoline in a Hercules direct injection mechanical fuel pump diesel when I got a load of summer fuel in the winter and it ran fine except it wouldn't idle fast enough.
Mercedes actually published formulae for mixing gasoline with diesel in the winter for their older mechanical engines. Maybe not a great idea for modern electronic super high injection pressure engines. But I will categorically state that a small amount (like the residual you'd end up with after emptying a jerrycan) of gasoline in diesel fuel will not affect the engine in any way.

The owner's manual for the 1970's-era MB cars specified that up to 30% gasoline could be used to prevent gelling in cold temperatures, believe it or not.
I'd agree that up to 10% gas in a mechanical injection motor should be a non-issue. I'd be surprised if newer motors are that sensitive but I don't have any experience in the matter.
