Fuel tank for diesel
 

Searched the forum for which fuel tank is best for my '68 GMC C30 that is receiving a '93 12 valve Cummins. Came up with the 31 gallon suburban tank and want to know if a galvanized steel tank is ok or should I go with a poly tank? Seems that diesel fuel brakes down galvanizing over time. Thanks in advance!

You can get a 40 gal diesel burb tank and use it but it may take some modifications to get it mounted in the 68 Frame. I had one mocked up in my 72 C30 frame so it will fit.

This is one of the tanks that come up for the diesel engine burb. Says in the description that it is galvanized....

There is another that says its Ni Terne steel. I like the 31 gallon because it doesn't hang down as much.

I know the ford diesel tanks are galvanized inside. I've never seen any issues with the galvanizing coming off on them. The tanks usually rust out first. :lol: I put a new galvanized 40gal burb tank in a 89 V2500 and I haven't heard from the owner in along time so all must be well there.

Thank you for your reply, exactly what I was wanting to know!

Neighbors F450 just lost both plastic tanks. Made a mess of the injection system. Took out the pump and lifters according to Ford.

What do you mean ( lost both plastic tanks)?
Diesel doesn't eat plastics.
