"vent hose should end higher than the tank"

Yes and no depends on where your filler is.

If you have the filler at stock location by your door then when you fill and the vent is below that level then you could have a situation where gas will go in the fill then flow out the vent.
So you want he vent exit as close to or above the filler hole.
if you have a bed fill location then putting the vent on a crossmember or near the truck bed is high enough. From the looks of your build thread unless you changed it this is the case.


are you going to put a charcoal canister on it so that you don't have the vented gas smell?

In my scenario for that i ran the vent up and inside the sheet metal above filler on door then back down so the top loop was above the filler. then back under the truck and into the charcoal cannister then vented.
