Gas leak

[Sambo1959]

I have 2- 150 gallon gas tanks on my 30sport proline. I had it pressure check and change out gas sender gaskets was told gaskets were leaking . So when I went to fill the tanks I noticed when I was out in the water I smelled gas so turn around and went home drain the gas from the biegle pump. Its about 3 Gallons I got out of it and stop leaking can anybody tell what they think i let the boat set for over night came back no gas in the biegle pump is it possible I am over filling the gas tanks

Don't know the year of the boat, but if its old enough it may be the fill hoses. Ethanol fuel eats the hoses

If it is the sender gasket that is leaking, you might try Perematex Permashield Gasket Dressing and Sealant #85420 on a new gas gauge sender gasket to stop it from leaking. The stuff is avail at Autozone (and likely other places), although they may not know they carry it. It worked real well for me....

No, overfilling will cause the fuel to flow out the vent. No fuel should ever leak inside the boat. As stated, check the fill and vent hoses, and make sure to seal the sender well.
