edit: the following info is misleading

I see where you're going w/ the 'no fuel out, air in' idea... gotcha.


My personal dilemma with the "fuel filter air pocket build-up" theory is, as you mentioned, the fact that the system is self-priming.

The lift pump, under normal operation (and e$pecially now that you have rebuilt your$), is always over-fueling the system. The only way air could build up in the fuel filter would be if the LP was pumping more air than fuel....


Perhaps I am missing a crucial diagram, but I thought that copper washer (7f ?) was the seal for the plunger in the barrel / perimeter of the DV and there is no fuel in the chamber around its outer diameter.
