Ok I got another project boat. Sorry not a jet. It is an 89 Baja 190es. Rotted floor, stringers, bad motor the whole works. Only thing is that the hull is mint. Not a scratch on this thing. Anyway, I want to build a new fuel tank for this and mount it under the back seat. I looked online at Moeller tanks and nothing will fit. I know I know...but it's not coast guard approved. Well I tell you what the alum. fuel tank that came with the boat should not be approved either. You gotta see the bubblegum and snot welds. How do they get away with this. So who sells a 2" filler neck that has the little groves in it and it curved. Sounds like a phalic symbol.

Call Tank-IT in Lake Havasu. They sell me supplies all the time.

Went on River Daves and didnt see the link.  Its Aluminum gas tanks.net or the buggy shop.  Good luck.

Thanks for the links. I am still looking. I will probably just end up making one.

when i build my tanks, i just used a 2" pice of aluminum pipe and rubber fuel hose

If you cut the old one off I'd leave some meat around it. It would be reinforced so to speak, then its an easy lap joint to weld up.
