    A little fuel system help please

    These pictures are from a 2012 PolarKraft with a Yamaha 4 cycle. There is gas getting into the bilge, but it seems to be only after fill ups.

    Can anyone explain to me the fuel line routing? The Fuel inlet is the large hose in the front, and the pickup is one of the 2 hoses in the back. I know one of the lines from the flvv goes to the charcoal canister, and then the vent. What do the other 2 lines do?

    Thanks

    Are you running rec fuel or regular auto fuel with ethanol? I know your boat isn't that old but the large fill lines are failing from ethanol in the gas... it seems to be accelerated if they have low spots where fuel sits in the hose. My boat is an 09 and i had the hose disintegrate and was leaking on fill ups you may want to look there. Those other hoses are vents to the canister one of the larger ones probably goes to the deck fill fitting if it was made in CA or where the pumps have vapor recovery nozzles.

    Fill it up with the floor off and see what happens. 99% chance it's coming from the fill hose, or one of the fittings that you can see in the pictures.

    EDIT: You can pump air into it as well, just be careful as it will blow up like a balloon.

    Big hose at front is the fill. Ive seen alot of these failing do to ethonal gas laying in tyem especially if they have bellies in them.

    The rear most is the vent and the one just in front of that is the pick up. Not sure what the black piece in the center is. It appears to run with the vent. Where does it go? Got a better pic?

    Look em over good (including the gaskets) and if you can't find an issue pressure test the tank.,

    ...the gasket under the sending unit is also a trouble maker...
