Dropping fuel pressure
My fuel pressure drops as much as 12psi when I apply throttle. It will stay as low as 35psi until I push the pedal down enough to get boost.
I only noticed this problem after installing a new Trex and Walboro 255 intank pump. Can anoyone help? BTW I have stock lines and rails, 30# injectors, 6:1 FMU, and a new Kirban Regulator set to 45psi (vacuum off). ------------------ 1994 Mustang Cobra 308ci, Vortech S-trim 11#, ported GT-40 heads, E-303 cam, FMS 1 5/8 headers, BBK Offroad H-pipe, 2-chamber flows, and several other goodies.
