key on prime/fuel pressure question

[Lone Watie]

When I first installed my gauge and turned key to on (no start) my gauge would briefly go to 5-7 PSI for the prime prior to normal start. I had to close my needle valve a bit to control some gauge needle jumping and noticed that for the key on/no start prime I now just get a quick movement up to maybe 2 psi, should I be worried about this? Running pressure are above minimums at idle and driving. Thanks.

My gauge pops 13-15 PSI and falls... With just a key on no start... Cranks at about 11-12 PSI and runs at 17 @ idle and 15 @ WOT... As long as while the engine is running the pressure never falls below 10 PSI you should be fine...
