NOT fully understanding this......
initially key in #2 gets pressure at the schrader valve (gas comes out like a geyser)
With the key still at #2 after time and that geyser is released, then there is hardly any pressure. SO pump does not run continuous in #2, only initial run/up pressure??
Back to my test, I build pressure with key in #2, wait and after 3 min or so there is NO gas on the rag and the pressure at the schrader valve is a tiny "poof" sound and NO gas released.
SO I am leaking pressure somewhere else??
(and its dry at the fuel rail connection at back)
THANKS!
