This is strange, i have a Aeromotive 1000 fuel system and have a sparatic pressure issue. Usually have 37psi at idle, when i get on it then let off and try to just cruise the psi drops to 14-20. it falls on its face when i try to get on it. rebuilt the Regulator and replaced the relay for the pump, no change. Mods that may help you guys help me: MSD DIS4 plus, Diablo, 60lb inj,full Aero fuel sys.
