Hi Chris:
I ordered my tank from California Import Parts. Most vendors seem to
sell two types of tanks, the 68 mm opening and the
48 mm opening. I measured my old tank and it was approximately 68 mm,
though according to ETKA, it is a different part number than what I
ordered.
The difference in size between the new tank and the old tank is about 1
mm and this allows the grommet to move around more than on the old tank.
I am not sure if this is just sloppy manufacture on the tank or the
grommet (though the grommet was supposed to be from VW). Anyway I am not
sure if it will seal as well as on the original equipment. I was
wondering if anyone else had this problem? I will test later tonight
with some water to verify before I install the new tank. I was just
wondering if anyone had used a sealer on the main grommet (per
Bentleys).
As an aside there are three grommets are available for the different
tanks. The 251-201-139 (nominally 68 mm OD, and 58 mm ID) for use with
58 mm OD metal fill tubes, the 251-201-139A, 48 mm filler neck seal for
the plastic fill tubes, and the 251-201-139B (68 mm OD and 48 mm ID) in
case you are mixing old tank and new tube. It seems that only the one I
ordered will work.
