I have a kind of newby question, I cannot remember what stock fuel pressure should be with a stock regulator. Shouldn't stock fuel pressure be 40-45 psi with the vacume line hooked up. I have a stumble upon a load. I think it is the filter, My pressure is 30 psi until you load the engine then it jumps to 40, but it quickly drops back down to 30. Again i think it is the filter, please help me.. Humor me.. thanks Guys..
Oh and anyone intrested in a 95 firebird a-4? 3800 ?

Thanks again

 

The pressure should be around 41 psi with the key on and idleing. 30 psi just isn't going to cut it. Check the filter, then the pump. Good luck.
