does anyone know how the factory fuel tank vent is set up? i added my auxilary tank and it leaks out the factory tank vent. i was going to vent it higher than the auxilary tank. i looked under there, and couldn't reach my hand in there very well, so plan on dropping the tank this weekend. looks like a tee of some sort and the hose was running back the frame but the leak looks like its coming from the tee. just wondering if theres a fitting in the tank or what?

 

If your auxilary tank has a vent and it feeds into your factory tank you could probably just block off the factory vent. Otherwise I'd say it's gonna have to be higher than the aux tank.

 

hey, i thought about just blocking it off since i have a vent with the auxilary tank but i thought if i didn't have the tee valve open all the time, i better just keep the factory vent. i went ahead and just ran a line up along the tank and clamped it to the inside of the bed out of the way. so far, so good , no leaks like last time i transfered fuel over! thanks....
