I've been told by many people that honda fuel pumps do not go bad. They either work or they don't work at all. I changed my fuel filter not long ago, the pressure was like that before and after the new one. Also have an aem fuel rail. At idle the psi is at 22 and when i give it gas it jumps to about 30. When you hold a steady throttle the pressure drops back down to 22. any suggestions?

thats how they normally go... either work or dont work.. but if there is enough resistance, it will not work like it should. do you have an adj regulator?? and if your car is stock... you shouldnt be running one of those rail anyway. stock is good for over 400hp
