Tii Fuel Pump Seal Advice PLS

[PaulTWinterton]

I removed the brass outlet on the pump. There is a unique copper washer to seal it against the pump. Unfortunately the washer is dead, crushed.

I looked everywhere locally and can't find a supplier. Short of converting to a 5-Series pump, anyone know where I can get this copper seal/washer?

This pump is young and has years left on it, don't want to lose it.

Thanks for reading and replying.

look at mercedes/saab/volvo/vw electric pump parts suppliers

for the seal ring you need ?

it should be just a common copper flat seal washer from

any metric bit supply bin

i know this isn't your pump,

but your looking to seal the fitting

at no.2 here ?

[PaulTWinterton]

Yes, the outlet valve has the copper seal at its base. I tried local autoparts shops as well as BMW and industrial fittings suppliers.

I could find the right ID and OD but the thickness is greater. The valve bottoms out if the seal is crushed too much.

I'm not sure how to ask Mercedes/Volve/Saab for the part, if I don't have a # or reference to their pumps. Ideas?

Belt sander.

Belt sander?

I did smooth the surfaces, but I'm sure the seal is crushed too much. As I said the valve bottoms out before a seal is achieved.

We're essentially talking about a copper washer, right? I mean, buy the one that's a bit too thick and mill it down. Copper is soft...

What I found is that the correct washer is thicker than usual. In my search I found correct ID and OD but too thin. Nobody that I found has a thick enough washer. Using a thin one, the valve bottoms out and does not create a seal.

Mesa Performance sells rebuilt pumps, maybe they can sell you the washer?

Oh. Guess you need to reverse the belt sander. ;-)

I guess in theory you could use 2 replacement washers... but...

... something can be sourced, or made :-)

I had that "problem" .... I liberally applied some Form-A-Gasket on both sides of the copper gasket & reassembled .... no more leak.
