The 8 psi was 1 minute and 55 seconds

Edit: per A Gal
I would have to raise the regulator pressure to get a acurite reading. reg is dumping fuel because it's getting close to the regulated 9 psi

I would try that...... raise the pressure to 11 or 12 and then do the test at 9psi.

If you want to run 9psi system pressure, it needs to maintain that pressure while pumping a gallon in under 85 seconds.
