Thread: PAS pump o rings

I have a slow leak from somewhere near the bottom of the pump (where the U shaped hose exits at the bottom and goes past the sump), rather than replace the hose I was thinking a flush and o ring replacement would be an easy start and then replace the hose if it persists.

Before I do, does anybody know the o ring size or part number and I assume I can just replace that from the bottom without taking the pump off?

Comments/thoughts?

That was my first thought but it doesn't seem to be. There seemed to be a lot of gunk all over it from the top down so I've cleaned it up to see if it's more obvious.
