340 LPH Fuel Pump and Fitting Kit for LS Engine Swaps
If your LS swap has been plagued by pressure dips during aggressive throttle this 340 LPH Fuel Pump and Fitting Kit was designed to ensure steady delivery from a 1991 through 2005 GM fuel tank. It combines a tank mounted pump calibrated for 340 liters per hour with factory spec fittings and reinforced hoses to fit around brake lines and exhaust tubing without clearance issues. Installers will appreciate precision machined connections that lock in place and resist vibration under torque cycles. Whether on highway runs or spirited track days this package maintains consistent fuel pressure so injectors and rails stay primed at all times.
Custom Frame Rail Mount Design for 1967-1972 Chevy Trucks
The tank's custom frame rail mount was engineered to match the contours of 1967 through 1972 Chevy truck undercarriages, eliminating the need for trimming or aftermarket brackets. Precision formed reinforcement points align with existing chassis holes, so installers secure the unit with factory fasteners for an authentic fit. This approach not only preserves the original frame integrity but also reduces vibration transmission by distributing load across a broad surface. A durable protective coating guards the steel assembly against road debris and moisture, extending service life without adding bulk. As a result, the tank integrates seamlessly into restoration and upgrade projects, simplifying alignment and reducing installation time.
EFI Style Internal Baffling Prevents Fuel Starvation Under Motion
Internally baffled compartments replicate factory EFI tank design to control fuel movement during acceleration, braking and cornering. These sealed chambers trap enough liquid to feed the pump continuously, preventing air ingestion when the vehicle's attitude shifts. By maintaining a stable fuel head, the design protects high-output engines from lean conditions that can cause hesitation or misfires under load. The arrangement also eases pump operation by reducing rapid level swings, which cuts down on motor wear and electrical stress. Technicians benefit from consistent performance at every throttle position without the need for external surge tanks.
Walbro 255 LPH Pump Delivers Fuel for Up to 550 HP Engines
At the heart of the system is a Walbro 255 LPH pump calibrated to supply enough volume for engines pushing 550 horsepower or more. Its robust motor and impeller assembly handle sustained high flow rates without overheating, ensuring injectors receive a steady supply even at wide open throttle. The unit has been tested for compatibility with modern ethanol blends, so it resists swelling and maintains clearances critical to performance. Designed for use with pulse width modulation controllers, the pump modulates output to match engine demand, reducing current draw at light loads. This intelligent response extends component life and prevents fuel rail pressure spikes during rapid throttle transitions.
Integrated Sending Unit and Bed Fill Neck Enhance Driver Convenience
A precision 0-90 ohm sending unit installs directly into the tank, offering factory-gauge accuracy without additional resistors or calibrations. Its arm and float assembly track fuel levels with minimal hysteresis, so dash readouts remain true under slow evaporation or slope changes. The innovative bed fill neck delivers a wide opening above the rear rail for fast, splash-free refueling and fits into original filler locations for a stock appearance. By combining accurate level sensing with a driver-friendly fill interface, the system streamlines routine maintenance and reduces the risk of overflows. The 18-gallon capacity extends range between stops, making it ideal for long trips or heavy work cycles where downtime must be minimized.
Engineered for precise fit and consistent pressure delivery to keep your LS swap running smoothly.
