Gas tank interchangeability
Hey guys -
I'm getting rusty on some of my FC knowledge so I figured I'd see if you can help me out here.
Buddy has an '86 GXL that has sat up for about 6 years. Gas tank is in bad shape, we think the fuel pump is seized up, and I think he'd be ahead of the game with a good used tank and pump/float assembly.
I seem to remember there were different versions of the gas tanks, like convertibles had a different one, 89-91 had more capacity, etc. Anyone know for sure what tanks will work/bolt in? He has a line on an '87 turbo gas tank here locally but we're not sure what shape it's in.
Thanks!
Dale

Absolutley Karack is right.
And no difference between Coup and Vert tanks. S4 tanks are S4 tanks, S5 tanks are S5 tanks. And as Karack points out, the two mounting straps for S4's only work for S4 tanks. S5 tanks being bigger need the bigger S5 straps to mount.
Also know you need a S4 fuel pump assembly for a S4 tanks, and S5 assembly for S5. S5 tanks are simply deeper, so assembly is longer.
Also, the S5 assembly has a detachable pigtail at the assebly while the S4's isn't detachable at the assembly. So be sure and grab the pigtail if you go S5 tank into an S4. In a Vert at least, the other end of the pig tail connects behind the plastic panel. So you have to pull it to get to it.

if you're going to to the trouble to replace the tanks, I highly recommend replacing with the S5. If only to make it easier to pull and detach the pump assembly to work on down the road. And that extra 2 gallons might bail you out one day. If you were closer, I have an S4 tank I'd give you for what I'd get from an aluminum recycler.

OK, for what I'd get from a steel recycler.
And, I agree no connector is better than having one from a durability standpoint. My position was simply from a maintenance standpoint. Not having to pull panels to get to that buried connector just so I can pull the assembly for bench work of the assembly is prefereable to having to.
