As I can see, the only place the gas tank in my bugeye can vent pressure is
through the gas cap. In checking out the bottom of the cap, there are two
small holes near the center and two more holes near the outer radius, past the
rubber gasket. I assume these holes accomplish the venting. The problem I
have is pressure building up. I found that when on the cap also seals tightly
against the rubber collar fitted between the body and the filler tube, so
the cap can't vent even if it wanted to. I have verified that the tank is
tightly secured and the rubber collar seems to be in place correctly. Looks
like my next step it to trim the top of the rubber collar to create a gap to
the
cap. Before doing so, I wanted to check my logic with the group.
Thanks, John
