[Public-List] fuel tank vent

[Gordon Laco]

Hi J -

I worried about the same thing.  When I installed my second tank I bought a
check valve that porported to be designed for fuel tank vent lines.  It
worked.  I got it from big bad West Marine... I forget what it cost etc but
can say that it worked.
