I just picked up a 89 Jeep wrangler 2.5 liter 15 gallon tank from Advance auto parts. I got the idea from mrhino's build

I have not installed it yet but here is what I think
Pros:
I like that the bumper almost completely hides it.
Cheap paid about $100 for a brand new one.
Appears to accept common GM sending unit/pumps with slight modification
Internally baffled
Cons:
Filler tube is only 1 inch
Only 15 gallons
hope that helps
Mike
