Seems the auto parts store do not carry it anymore. My buddy suggested lowes. Anyone else have some suggestions. Whoops I'm a bluebie again. Time to pay up.

I think it would still be degraded by the fumes of the fuel.
If that was in a pickup bed I could see it, but not in a pass compartment...I think Jess has the back wall still on his truck, maybe that would be OK for him.
I just replaced mine. Mine was like 2 1/4 or 2 1/2" i think. Maybe bigger. No one had it. Couldn't find it anywhere. Then I called a local boat dealer. They had it. I think I paid around $20.00.
and of course for my set up I only needed 6"
I did call around and the local advance auto sold it also, but only in 3' lengths at around $30 IIRC.Since I was measuring some other stuff I decided to measure what's needed for my suburban too. I got at least 24" of 1.75" id filler tubeing and 2 #28 hose clamps. For the vent is 5/8" 12". I measured from the center of the tank out since I didn't have clear access to the top of the tank without contorting myself and I don't feel like doing that right now.
Does it need to have bends or be straight?
I worked at oreillys for a few years, they cant get factory replacements but they can get some fuel resistant filler hose from gates. I dont remember if it can be bent or not though, it may only be straight pieces.
If you want to check into make the counter guy dig out the gates book and look through it. I know most parts guys around here dont like using the books so I usually just have them give me the book and I find what I want.
I'll call the marinas on monday. My old hose is still good, it is just too short to fit where I want to mount the cap/neck assembly .
