I'm looking for an aftermarket inline fuel pump to run with a 97 b2300 motor. The manual says that the FPR should regulate the pressure down to 30 psi at idle and around 39-40 under normal driving conditions. But it says nothing about sustained higher rpms. It also says nothing about gph, which I assume also matters. So what can I get for relatively cheap, online or at a parts house, that will suit my needs? I've tried summit, speedway, google, here.... Also tried shucks and pepboys, was thinking maybe napa and national today.
