New install fuel tank

[Paradise David]

Over the last 2 weeks, I have installed a 13 gal aluminum fuel tank.

In the front, under the deck. not an easy install.
new thru deck vent installed.
new fill neck, 1 1/2 hose connected to fuel tank
new sending unit
new fuel gage

everything plumbed like it should be, all complete.
I put only 6 gallon of gas than took it back home, check for leaks, seems to be all right. Went to work.

Next day, went out to wire in the fuel gage and I could smell gas under the deck.

I immediately drained the tank, than pulled the gas tank out.
There was no fuel on the floor but the wood I use to hold down the tank does have a gasoline odor to it.

I wondering about condensation?
The tank does NOT have a leak.
Where could the smell be coming from?

new thru deck vent installed

Maybe this what your smelling.
The vent should go outside the hull.

Thanks for the reply.
When I crawl under/inside the hull I can smell gas, the vent is installed at the bow, thru the hull topside.

above is the vent I purchased from Iboat and installed.

Re: New install fuel tank

Gas fumes are heavier than air. If the vent is topside, it is possible that the vented fumes are settling into the hull. You should make sure that the vent is off-board to the side.

Good Luck!
