High Flow Fuel pumps by Quantum Fuel Systems
The HFP-368H GM-Specific 255LPH Intank Fuel Pump has a number of design advantages compared to a Walbro 255 pump, or generic offshore unproven "255LPH" pumps sold by fulfillment warehouses instead of real performance parts distributors. Venturi port functionality allows tank to be used all the way down to empty, just like OEM pump, instead of having to keep it 1/4 full like generic performance pumps which aren t designed for the 96-01 Vortec sending units.Our 255LPH pumps can also be used as direct replacement pumps, without overpowering the factory fuel pressure regulator. This is not the case with Aeromotive Stealth 340LPH and Walbro 400LPH intank fuel pumps. The advantage of modern return-style fuel systems is that they only use as much fuel as the engine requires. Any unused fuel is automatically sent back to the tank via the return line. Using a 255LPH pump instead of an OEM replacement will simply provide room to grow if any modifications are planned for the future.
Except for a faint "wheen" during pump priming, Quantum pumps are nearly silent. Walbro pumps are notorious for their loud vibrating "hum" during operation. Quantum pumps are manufactured to our specifications to balance volume, pressure, and turbine impeller angle to prevent overheating of the fuel (a known issue with Aeromotive 340LPH Pump, and Walbro New F90000262 400LPH Pump).
We back every single pump with a Lifetime Warranty. Walbro requires that you pay a $40 "warranty fee" when you send the pump in which often results in them telling you it was installer error, not pump failure. Quantum pumps are flow verified by RC Engineering and are guaranteed to flow higher than any 255LPH pump on the market.
