Since their debut in the early 1990s, Walbro 255LPH intank fuel pumps have been the industry standard by which all other 255LPH fuel pumps are judged. Walbro?s first design was a center-inlet 190LPH pump for the Mustang 5.0 and Buick Grand National. Later, Walbro added more inlet configurations and increased volume to 255LPH, allowing their pumps to be installed into just about every modern vehicle on the road today. The benefit of today's return-style fuel systems is that any unused fuel is automatically returned to the tank via the return line, which makes Walbro intank pumps suitable for turbocharged, supercharged, as well as stock replacement applications. These fuel pumps can safely support 500hp, or 600hp+ when used in conjunction with our hotwire kit.
All Walbro fuel pumps are Made in the USA.
Quantum Inline High-Flow Viton Fuel Pump Check Valve 8mm / 5/16"
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.
