In Tank Fuel Pump O-Ring

[fjmuurling]

Does someone know the size of the o-ring (A082L6164F, Parts Manual 44.03D item 6) which is used between the RHS tank and the mounting flange of the in tank fuel pump.

Does 90 x 6 mm sound familiar?, my old one is deformed so not sure about the size.

I don't know off hand... I do have one lying around that I could measure, though it did shrink after removal...  I'm not sure if it would be back to normal size or not.

 

The replacement pump that I bought, came with the proper o-ring.  BOSCH 69218 from Amazon.

The 90 x 6 (mm) is not the right size, the I.D. Is too small, the cross section size looks ok.

Measured the flange in the tank (should have done that before, but didn't expect the old one to shrink in diameter after removal) and the I.D. is 95 mm.

The cross section of the old one was oval shaped measuring around 7 by 5 mm so hence the 6 mm for the new one.

New Viton o-ring of 95 x 6 is on order, hope this one is the right size.

The 95 x 6 (mm) is the right size for the o-ring. Fitted one today, sits fine in the recessed groove in the tank and didn't need excessive force for closing of the locking ring. I did put a little bit of grease on the locking ring in order to reduce the friction between the locking ring and the flange of the fuel pump.

As a material i chose viton instead of the standard nbr.
