Wonder because I am shopping around for a new fuel tank, pump and whole 9 yards... up to what year would be compatible with my truck? I have an 81 F150 4x4.

I am just looking to replace and have the tank up front. (Because I have plans to buy the other later.)

I keep looking at the Spectra F6A but don't know if it is the one for my truck.

 

Here is the link to Spectra's catalog with all specs etc.

As long as the gal# is the same, i think it should fit atleast up to a 96 for sure.
Im scavenging a 96 now for my 86. Next thing i get is the front 16gal tank and filler neck.

 

1980-1984 uses one type of tank

1985-1986 uses another.

The differences are in the size of the hole for the sending unit. The 1985-1986 are larger diameter.
