I just can't tell if there is anything wrong with the one I have. I think I may just order another one with the gasket anyway since I don't see what else it could possibly be.
My current pump has a part number ending in '3,' but this one ends in 4. Blue-s, what does yours say? I'm gonna call tomorrow to see if it fits. When I click on info, it says it fits all models up to 2004 whether it be boxster or boxster s EXCEPT for the 2000 boxster s. This sounds like a mistake and I will call to confirm this. The Laso part number is the same and it says it is indeed compatible with the 2000 boxster s.
