Inconsistent fuel pressure

[SMack]

I have a 511 striker with a six pack Holley Black electric pump Holley regulator and 0-15 psi gauge. I set the pressure to 6.5 lbs all is good. But then the next rime I go to the car the gauge won’t read? I take it off blow air across the fitting not directly into it just lightly to get the needle to move put it back on and it works but I alway s have to reset the pressure. I have 2 of these gauges they both do the same thing. Thoughts??
Thanks Guys,
ED

Yes, buy a Carter 4600HP pump. Internally regulated, no reg reqd, quiet, cheap, will last forever & can theoretically supply a 1000 hp engine.
I DO know of a Carter elec pump that was replaced........after 19 yrs......in a daily driver.
Not because it failed......owner thought that it had earned it's 'retirement'....

Needles on mechanical fuel pressure gauges get stuck sometimes. One of mine needs a thump with my finger every once in a while

Understood. All the reviews on the gauge I use are not good. Going to upgrade that first and go from there.
Much appreciated Purple Beeper.
