Quantum 255LPH Fuel Pump Mazda 323 GTX 1988 - 1989
This is the exact same pump we run in our 86 LX Coupe shop car powered by a Ford Racing 5.0L Coyote motor which makes 407rwhp/388rwtq. Members on http://www.corral.net are using this pump with supercharged/ turbocharged combos making over 500rwhp.
Refer to the flow tests below done by RC Engineering. The higher the pressure, the more our pumps outflow their Walbro equivalent.
A common side effect of high volume (and OEM) intank fuel pumps are their inability to maintain static fuel pressure when the vehicle sits for any extended period of time. This leads to a "hard starting" condition where the starter must engage continuously for 3-4 seconds (or longer) before the motor will finally start. This side effect is commonplace with all high performance, high volume fuel pumps including Walbro, AEM, Aeromotive, and Quantum fuel pumps. Our check valve resolves this issue once and for all, and can be used either intank, or externally. It features a high-flow design which uses viton seals and stainless steel internals which are compatible with modern pump gasoline as well as E85. This check valve will not significantly alter the flow capabilities of your pump, but it will make sure that the car starts instantly, every single time. We recommend installing an inline check valve even with a brand new pump, so the tank doesn't need to be dropped again a few months later.
