Subject:      Burping gas tank filler problem solved!!
Content-Type: text/plain; charset="iso-8859-1"

Well troops, it's amazing how simple things can cause the big problems.

Both of the expansion valves in my fuel system were okay, but I replaced
them anyway.  However, I accidentally shook loose the breather pipe under
the gas filler(I was going to pull it anyway to look for foreign objects
before I put the tire back on), and lo and behold, here's a huge glob of
clear silicone all but totally constricting the vent hole.  Now when I did
the Wilfy fix for the crossover pipe, I vaguely remember putting a "dab" of
rtv to help seal the nipple type gasket, but not THAT much!  Yes, I feel
like a dumbbutt.  Be intersting to see whatthe others with this problem find
blocking their lines!!

Needless to say, the tank on my 90 GL fills up like it normally did prior to
the Wilfy fix kit.  What I still don't understand, is why it took a couple
of tank fill ups to have the breathing problems surface?  Silicone should
set up in a day or two.  Oh well, not argueing with solutions here.

For you folks suffering with this problem,  shake your expansion valves to
see if they are moving up and down before you order them, they are a little
expensive, $25 for the pair, and the grommets are $6 ea.  Checking that vent
pipe for kinks or blockage would be my first line of attack if I had to do
it over again.

You Syncro owners should do the same, check the vent pipe wherever it is
located back by the tranny and see what you can un clog.
