340 LPH LS Fuel Pump and Fitting Kit for GM Vehicles
Installing an LS engine into a 1991-2005 GM chassis often exposes the stock tank plumbing's limits and leads to fuel pressure dips under load, so the 340 LPH Fuel Pump and Fitting Kit delivers a ready replacement. Each precision matched adaptor is CNC machined to fit the existing tank opening with leak free seals while preserving factory gauge electronics for reliable level and pressure readings. The drop-in assembly secures under the frame rails of F-body coupes, full size trucks and other GM models from 1991 to 2005 using standard hardware with no custom brackets. A consistent 340 liters per hour flow and baffling to prevent fuel phase separation during cornering or braking help maintain injector pressure for smooth performance across the rpm band.
Precision CNC Machined Adaptors Ensure Leak Free Tank Integration
Each fitting is CNC machined from grade aluminum for precise tank opening alignment. This process creates leak free connections that withstand vibration and temperature changes. The threaded adaptors engage smoothly without extra sealants or brackets. Installers save time with straightforward service access and a secure fit. Factory gauge electronics remain integrated to provide accurate level and pressure feedback. The precise fit helps maintain consistent fuel routing under all driving conditions. Elevated sealing reliability prevents the performance dips linked to pressure loss.
Advanced Internal Baffling Maintains Steady Fuel Supply
Internal baffling channels fuel through multiple chambers before the pump inlet. This system prevents fuel slosh away under hard cornering and firm braking. It maintains a stable fuel column to avoid pressure dips and lean pulses. Vapor lock risk is reduced during sudden directional changes. The steadiness supports precise injector spray throughout the rpm range. LS swap projects gain consistent throttle response and tuning stability. Drivers will note reduced pump noise as fluid shifts are dampened.
Walbro 255 LPH Pump Supports Up To 550 Horsepower
A Walbro 255 LPH pump delivers a steady 340 LPH flow rate under load. It supports engines producing up to five hundred fifty horsepower without pressure fade. The zero to thirty ohm sending unit matches GM gauge electronics for true level readings. Sensor and pump calibration ensure accurate feedback without extra control modules. EFI systems benefit from reliable fuel mapping data at idle and wide open throttle. Startup and idle quality remain stable across varying ambient temperatures. Technicians find tuning easier when pump output and sensor readings align.
Underframe Mount Simplifies Installation On GM Chassis
The underframe mount design secures the assembly under rear frame rails of GM models from 1991 to 2005. It reuses OE fasteners to eliminate custom bracket fabrication. This eighteen gallon capacity tank extends driving range for road and track. Its compact profile preserves ground clearance and avoids suspension interference. Standard hardware and mounting points simplify installation and alignment. The sturdy base resists vibration and chassis flex under dynamic driving. Installers appreciate a drop in installation time and reliable part engagement.
A reliable choice for your LS swap project.
