Did you do any of the test I wrote-- above -??My problem is I need to get home tomorrow w/ wife and two kids, so me and wife can go to work Tuesday morning. I would love to support site vendors, but need to be on the road tomorrow. I can turn a wrench and have lots of experience of making things work. Just need to know how.
You are right, I looked it up an there are two lip seals and four "O" rings. Of course, GM probably wouldn't think of using standard lip seals, would they??The seals are lip seals--[very difficult to find] not o-ring--there is one o-ring where the primer cup mates the housing -where the three screws are.
