Bought the tester today. After the car had been sitting overnight, I had my dad turn the key for me and watched the gauge. It spiked up but then dropped back to only 20 psi and held steady. So he turned the key back and primed the pump again...shot up to a 'normal' reading for this car. Relieved pressure in the pump to bring it back down to zero, and primed it again....didn't have any more low psi problems, but first, is that any sort of warning sign? 20 psi is pretty low...

After it started working fine...with the fuel pump priming, it was at about 42 psi. KOEO, with the pump having already primed, it read about 36 psi. With the engine running, even though it was cold we flinched the gas pedal to bring the idle down to a slow one, and it read about 34 psi. Tapping the gas lightly caused only a loss of 4 psi or so.

So, is it operating normally? Thanks guys.
