Fuel odor

Had the same issue. turned out there was a pinhole leak in the plastic tank, replaced it with an aluminum one.

I mostly notice it when the boat has been covered. Fuel level doesn’t seem to matter. Going to try and slide the fuel cell out and inspect the gasket under the fuel pump housing.

Not that I can tell... It’s got a half tank now and it’s been sitting stationary for a while as I’m taking care of some other items. Pretty strong odor.

I found my fuel smell came from the fuel vent. I ended up putting a carbon filter on my vent hose. Maybe you have a leak but mine was from fuel sloshing around in the tank and pushing the vapors out the hose.

hows the top plate? top should be clean if not leaking or seaping out - got a pic of the top of your tank? I made a new set of gaskets and sealant and then sprayed with flex-seal - not pretty - but the smell went away - I could not fill my tank - when it sloshed it seeped out the top

My 96' Prostar with LT1 once did that same thing. While running the boat, behind the engine, there was a strong smell of gasoline fumes. After running thru all of those types of fuel system check lists, it turned out to be a unnoticed disconnected spark plug wire. I reconnected the wire and the smell went immediately away. Hopefully it is something as easy as that.

Mike, was the smell really strong, primarily when you’d take the cover off, and not as noticeable when docked or moving?
