Steven, your experiencing the same situation I am. My front pump sounds powerful and the car will run on just that pump. The rear pump is nearly inaudible and the car stalls as soon as you disconnect the front pump indicating it does not have the delivery capacity to support even running at an idle. I thought if soemone out here could disconnect their front pump breifly while their car was idling, we could confirm if this is normal operation. I'm not sure if a healthy rear pump would be capable of drawing fuel through a stalled front pump. My car has a 1.0 bar spring installed but I only get about .7 bar most of the time. Occasionaly, it does go to 1.0 and it's a great thrill but doesn't last long.
