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's 340LPH Pump, and Walbro's 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.
