key on prime/fuel pressure question

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.
