I am in process of purchasing this boat and found strong gasoline fumes when the access cover was removed under mid-bunk into fuel tank compartment.

Tank was pressurized to 3PSI and no leaks were found.

Mechanic spoke to Moeller mfgr of tank and indicates this problem arises from permeability of the tank. Has anyone else experienced this condition? What is the solution other than not to buy the boat?

I have a 2003 176 w/the same type of tank and do not have that problem with mine.
 
I had some problems with a 1998 270DA. I've found that the seal around the fuel gauge float fitting is permeable. I replaced it with a new gasket with sealing compound on it, made by Permatex (I forget which Permatex but don't use the regular stuff it does not work against poly ethylene) and problem solved.
 
If you can smell it then it's leaking. Have it fixed by the seller. Or I'd walk.

That statement does not apply to poly tanks.
To the OP. Many people with the poly tanks have complained of arriving at the boat & being hit with the odor of gas.Most have said that shortly after opening the boat up, the odor dissipates.

Is that a brand name or material. If material, is it ethanol resistant? Just curious. My regal had a metal tank.
 
I don't think I could handle smelling gas on my boat, Send my wife down to it and have her open it up and turn on blowers if some thing went wrong and she was hurt. Nope not for me... alum tanks for me.
 
How can it not apply? If there are gas fumes, they are flammable regardless of where they came from.
 
Did not buy the boat due to this. I dont know how you would distinguish "benign" gas fumes from "dangerous" gas fumes

I don't remember the exact term. I think it is the fact that the fumes which permeate out of a polyethylene tank never reach the "lower explosive limit" In other words, they stink but are not explosive. The figure of 24% concentration of gas fumes sticks in my mind. If I am wrong on that figure, I hope someone will correct me.
