67-72 Under box in frame Fuel tanks ideas

[freeride4011]

Guys,
I need a tank that I can install under the box of my 68 GMC 4X4.

Any ideas if there is a stock tank that will fit from a newer truck or do I have to custom make one?

Fill tube I guess will have to go thru the box.
I was hoping to figure out a side fill system but that would be allot of body work.

Any pictures would help big time.

Thanks guys the old girl is starting to look like a truck again.

Go to the FAQ. You can use a blazer or after market tank, and you can fill through bed, marker light, tail light and more...

Look under the venders section. There is a guy who sells complete tanks for any application. I think he goes by fuelcellguy or something like that
