I just got a valve out of an '82 in the boneyard.  Cost $5.  It's grommet
had turned to goo, but I�m sure the new ones are better. I have the one's
from Van Caf�, it's not worth messing around.  But I will tell you this, if
your grommet is still nice and hard and tight, don't try to replace it.  You
will break it trying to get it out!

Subject: Fuel Expansion Tank Valve Grommet: Use PCV Grommet?

Hi all.

Van-cafe has these:

rommet.html

but for if someone were in a pinch....

I'm looking at Dorman products (Some Dorman products sold as "HELP") and see
various PCV grommets that might work:

Measuring a spare expansion tank and new rollover valve, I see:

15/16"  tank ID, 7/16" valve OD. I don't know how thick the OEM grommet is
though.

Since a PCV grommet is likely rated for oil, would it be ok for use with
fuel or fuel vapours?
