[Vwdiesel] More Quantum Questions?

Mon Apr 20 19:00:55 PDT 2009

Hey, thanks! Knowing that will help save me some money! I like the fact that
when buying through ebay, if you are dealing with a seller with good
feedback, that they have a good incentive to treat you right. Sometimes I'm
a little suspicious that some internet sellers are just teens in their
garage with some stuff they bought at the dollar store or the like.

I don't get how you would use the spring with the bolt? Are you thinking
down inside the pump?
