Hello, I'll need your good assistance here, as I don't thin thi is right:
Before start up, and after the primer is used, the fuel pressure is built up, to .4, as it should, with the "wobble" pump, but as soon as I stop the pump, the pressure drops back to zero. Shouldn't it stay up ?

I think its allowed to post Scotts comments out of the beta forum as we had a discussion about this also:

Quote:
All the wobble pump does is prime the fuel lines. We have confirmation that the fuel pressure goes right back down after you use it, so the 4psi number is likely just a reference to confirm the fuel lines are primed and you can stop pumping.


so, yes, its normal and correct
