Quantum Inline or Intank High-Flow Viton Fuel Pump Check Valve 8mm (5/16")

HFP-FT3

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.
