Fuel vent hose question
https://www.ford-trucks.com/forums/9...vent-hose.html
I am replacing my tank, found a cheap used/new one.
My old one, was emissions but nothing was hooked up.
The new one is non-emission but I didn't think it would be an issue.
Well I missed the part about the filler/vent hose orientation.
The tank holes are flipped to each other.
example
O o =new tank
o O = old tank
No biggy I think, I'll just get a bigger vent hose and cross it over the filler hose and clamp it down.
Now I wonder if this is even possible without having venting issues.
Has anyone done this successfully or did you just replace the filler neck hardware to match?
You need to tape the fill hose and the vent hose together in order to allow the tank to vent while filling. If your vent hose is sitting lower than the fill hose the tank will not let the fuel vapor escape from the tank thus not allowing you to fill your tank.
We run into this issue alot in the body upfitter world. Lots of customers bring the trucks back to us with fill issues after they do a home install or a retrofit or it was too close to quiting time in the shop! When you start running 2-3 foot fuel fills you really have to make sure the vent hose is above the fill hose!

I agree seems like a silly question but it would suck to have to take it apart because gas keeps puking out at me.

I'll look for a filler neck, hope it's cheaper than the hose.
