gas cap vent

macojoe · #1 03-29-2010, 09:28 PM

Not a V20 but...........My boat has a perfect vent, but when the tank is full and I have the trailer up a little on the trailer to keep the water draining, the vent gets blocked by gas, The result is leaking gas out the vent.

I have thought about adding a second vent in the front of the tank so the air will vent there when boat is tilted. But that means drilling a vent hole in front of the tank?
So i was thinking of a vented gas cap, but all the ones I see still needs the small hose connected, which means still drilling a hole for a vent.

I know i can't be the only one with this problem, so what have you guys done??

Thanks

Normaly the vent port on the tank should be in the front section, if that is the case with yours, all you have to do is relocate the vent fitting more forward. Where is the tank fill fitting?

and there is no vent port in front of the tank. Drilling and taping a new hole is not going to be easy, CB said to try to find a Y connector for the fill??
I was thinking if I removed the fill hose near the gas cap and drilled a hole into it and put a smaller hose in it the fill would work as a fill and a vent?

That doesn't sound right. Maybe they used the second pick up(some times tanks have a second pick up or return for diesel) instead of the original vent pick up. Check to see if you have a fitting or a pluged hole next to the tank fill (on the tank), if you do, that should of been the vent.

It has none, maybe the put the tank in backward when they built it??

No, tank fill is forward, so is correct. If tank fill is located in the middle, then yes, is installed backwards.
