OK, so I have my poly blazer tank mounted, gas lines ran and working, and I have a 1 1/2" marine type cap installed on the rear fender. I bought a 1-1/2" filler hose on ebay, only to find the tank neck is actually 1/8" smaller at 1-3/8".... great.
My first though was to find a 1 3/8" hose.... must be an odd size cause I cannot find it anywhere! So I really just need to rig the filler neck so I can use the 1-1/2" hose I already have. I've noticed the guys using the metal tanks weld on an exhaust reducer and call it a day, but with the poly tank, I don't have that convenience. Only thing I can think of is slipping on some sch 40 pvc and epoxying it to the neck, but that seems like something the redneck PO I bought the truck off of would do.
So to my question, anyone know of a reliable way to make this oversized hose work?
