Source for fuel pump o-rings Options

[andreic]

My fuel pump (3 port, original fuel pump on the D-Jet on a 1972 914 1.7L) leaks fuel. I have read that it is relatively easy to replace the 3 o-rings (as far as I understand it, there is one body o-ring, and two others underneath the cap).

Does anyone know of a source for them, or the sizes of them so I can try to go to a specialty store and look them up?

Thanks.

I tackled this job
found out McMark had already done it

his advice, and my experience were similar
very difficult job without the bosche crimping tool

I ended up using a dremel after prying for an hour.
the factory crimps are difficult to open and difficult to re-close

I rebuilt 2 pumps.
one failed soon after
they look butchered

after the fact, it was my opinion that these should be done with a factory crimping tool and were not a good use of my time

If you go forward, I'd recommend you spend some time trying to take off the exterior case before worrying about the replacement parts. If you are successful in opening the case, the O'ring will be easy to measure at that point.
