hello,I have a polyethylene fuel cell mounted in the trunk of my car. it is ventilated correctly to the outside and none of the fuel lines have leaks, but I get a strong gas odor in the trunk and passenger compartment. does anyone know if this is common with the poly cells? does poly permiate fumes ? have to replace with aluminum cell to fix problem? Thanks, Tom.

Yes poly can and will permeate fuel vapors... unless
it has a permeation barrier molded into it(which MOST
of these cheaper cells dont)... but I must say that
I dont smell any vapors from mine.... you might want
to check the filler cap ring to make sure that is
sealed... also the cap. Where does your vent dump at
