The vented gas cap, does it only work when there is a hose from the tank to the cap, or does it vent its self?
I agree drilling the tank os not the thing to do!



Thanks Mike, Why would adding a 2nd vent be worse?? If I added one to the front it would not be blocked when boat is tilted allowing for it to vent, right?

I know that it being to full is the case, but even if I don't fill till it tops off and tilt the boat up it blocks the vent in the rear.
Why they ever vented it in the rear is beyond me!

Just like the old fruit punch cans, the punch would flow out slow with one hole but add the second and it flows like Tiger Woods, because you release the vacuum..
