lift pump output
Those figures above sound about right while at pressure.
I checked mine while working against no pressure. I drained the cannister and run
the drain line down into a calibrated container which held one liter. I used a stopwatch to measure the time while the lift pump was working. I would turn the key on , watch the fuel pressure gauge (also you can hear the pump working) and
click the stopwatch all at the same time. I would do this a number of times and
check for consistency.
I come up with an ave of 4. 338 liters/min=1. 145 gal/min=about 69 gal/hr.
The above posted figures show about 70% of what I come up with which sounds
reasonable when working against pressure.
