Factory 68 F100 Rear Gas Tank?

Post #1 by maxtrux » Wed Nov 21, 2018 3:30 pm

This may be a stupid question. My 68 F100 has a rear gas tank. I have no idea if it is original or an add-on. I was thinking that they did not come with a second tank from the factory in 68 but not certain. The older gentleman that originally owned it modified it at some point with an aftermarket speed control. In doing so, he unknowingly :oopsie: mounted the driveshaft speed sensor into the rear gas tank. The second owner removed the speed control but did not repair the tank. I am not overly comfortable listening to the gas slosh from the in-cab tank; however it works perfect.
Hoping someone can tell me if it is a factory tank or an aftermarket so I can find a direct replacement. I don't know how many years ago it was drilled into and feel it would be a better idea to replace than repair.

Reckon my next one should be from the 50s but I do love the early 60s falcon

Without seeing a picture of what the rear fuel tank and its mounting looks like this will only be a guess. Most trucks back then only had an in cab fuel tank an exception could be a truck with the Camper Special option specs. Back in the day there were also many companies and even welding shops that made custom accessory rear fuel tanks for pickups. Here is a listing of rear fuel tank see if it looks something like yours. http://www.lmctruck.com/features/fb/fb31a.htm

Now if you wanted to remove the in cab fuel tank for safety purposes or to give some more extra room inside the cab, many people have used the Mustang fuel tanks with good results. It's mounted at the rear of the frame rails at were the spare tire was located, it's a fairly easy bolt in job except that you need fab in the fuel filer tube and cap most often this is through the bed floor. On repairing your existing rear fuel tank it can be done so it's safe. There are still some radiator shops that can clean and do the repair on them. Good luck :thumbup: :nod:

I am still hunting for a project car to build but with my current low budget it's not looking so good. My Ex- Fleet of Sixes these are all long gone! :bang: 1954 Customline 223 3 speed with O/D, 1963 Fairlane project drag car with BB6, 1977 Maverick 250 with C4, 1994 F-150 a 300 with 5 speed.

That's a good idea. When it dries out a little here, I will probably see about dropping it and taking it to a radiator shop. If they can assure me that it is clean, I don't mind using it again. Thanks Bubba
