100+psi fuel pressure
I have a 06 redline, new aem e85 fuel pump, ZZP brfps, and 80lb injectors. Key on, engine off, fuel pressure hits 100+ then comes down and stays at about 45psi. Fyi I also messed with the regulator because I thought I just needed to adjust it. Also, makes a louder noise than stock. When engine is on, vacuum is only 15mmhg and pressure spikes 100+. Wont come down. Regulator gets vacuum, can remove line and has suction. Btw, also runs 93 right now, not e85. About to change my fuel filter. Any ideas besides fuel filter?
