[T3] On and off hard start FI 73 type 3 ?

[William Jahn]

I have the original 4 I removed in 2002 yet at the time I just placed them
in a bag and didn't know the O'rings shrunk and resulted in a leak. I know
some on Samba send theirs into rock auto who sends them out to another
place to be flushed and cleaned and flow tested as well as new inlet filter
screens. If they leak they are marked as bad and returned. They can't fix
the body O-ring leak. There is also another place who does this work. It
costs around $25 per plus shipping both ways.

 I have no idea what the replacements are other than they cost a fortune
and there are quite a few aftermarket brands out there.

 I thought about sending my old ones in but since they sat so long they
very well might leak at the O-rings.
