Any issues with using a new galvanised jeep gas tank for diesel fuel?

[Texan1983]

Looking to add a CJ5 jeep fuel tank in my dodge ram diesel as an aux fuel tank. Shouldn't be any issues running diesel in it is there?

Thanks!

It's not a good idea diesel and galvanized are not compatible,an oldtimer told me once it was the sulfur in diesel that reacted so today's ultra low sulfur diesel fuel it's not as big a problem as it once was.

so a painted steel one would be better?

Here's a good,economical way to put 3-4 more gallons in your existing tank. It simply relocates your vent up higher in the vacant part of your tank.
That'll buy you 45-60 miles.
Mine's been in for eight yrs now. No issues

If you get an aftermarket replacement tank by Spectra it's made with their "Ni-Terne" steel, they use that same material for both diesel and gasoline tanks. We have a Ni-Terne steel Bronco gasoline fuel tank in a diesel truck, been years with exactly zero problems.

I'll look into it, thanks

Is that Jeep tank one you happen to have on hand, or has it been referred to as one that fits the space you are looking to fill? If you don't have the tank yet you might find a poly tank meant to go in your vehicle as a transfer tank for not much money.

 

[Texan1983]

it's been the best fitting tank I could find. I looked into poly but they are usually over twice the cost.

I did find a poly version of this cj tank for 175 which is still much cheaper than a lot of the generic or custom sized fuel tank tanks... im trying to use the space in the spare tire location to use as aux transfer tank. the Titan tank that is designed to go there is over $500! crazy money. I think I could build the whole system for under $200...

Truth^^^

Yes, but I would use a poly tank if its within your budget. Over time, water in the fuel and condensation will rust the tank from the inside out.

If you ever plan to use biodiesel, stay away from a galvanized tank. The biodiesel will etch the zinc coating right of the surface and put it into the fuel.

Just a thought, you might be able to use Glyptal paint on the inside the tank if rust is that big of an issue. Glyptal is formulated to resist petroleum and its distillates.

Great idea, maybe I'll be able to put in the 51 gallons my tank is spec'd for!

Standard, from the pump, #1 or 2 diesel will do it too. Biodiesel will unseat the wax buildup in the system and may create further problems.
