Ahh, finally someone who knows what I am talking about and didn't say "you are wrong". I decided to do as you stated here and turned the key twice before running the engine. Voila, it fired right up. This is what I am talking about. The check valve is not functioning, so there is no residual pressure and there fore takes a while to fire up the first time. I guess i was incorrect about the check valve being there to keep the pressure. I could not reproduce the explanation very well from memory. (my mind is worn) I think the mechanic believed that if one part of the pump is out, then the rest will fail soon. maybe that is wrong, but I do believe that check valve is out. And I do not want to turn the key twice every time I start the engine. Maybe I will pick up a pump. nathan 1970 fastback The check valve in the pump has nothing to do with the 31 psi pressure. That is strictly controlled by the regulator. The only thing the check valve does, is to help maintain residual pressure in the system after the engine is shut off. I am using a pump with no check valve,(not a VW), and have no problems with starting except that I usually turn the key off and on twice before I hit the starter. ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
