OK, not sure what the "white pin" is. But there is a hole at the top, behind the air dome section. It allows the air dome to "see" atmospheric pressure. The air dome really should be called an accumulator, but I didn't have anything to do with naming it.

Ok,up top where the hole is on this pump mine also has that,but you can see the white pin that has a spring on it,on the inside.My pump also has a hole next to that.Still trying to figure out how to post a pic

OK, I haven't seen one with a hole exactly like that and without taking it apart and looking, I can't tell you any more than I already have.

But tell ya what, you wouldn't see me worrying about it if it were mine. If it works and doesn't leak, ignore it and get on with life.

Re: Fuel pump ?
