340 LPH Fuel Pump and Fitting Kit for LS Swap Applications
Tailored for GM 1991-2005 chassis conversions the 340 LPH Fuel Pump and Fitting Kit ensures consistent volume from the stock tank to meet LS engine demands. By matching precision machined fittings with factory ports and using a bracket that ties into existing frame points installation eliminates adapter hunting and trims labor time. The integrated Walbro pump sustains flow under both steady cruise and sudden throttle transitions to prevent lean spikes that cause hesitation. With parts engineered to clear heat sources and suspension components this kit delivers reliable fuel delivery while preserving chassis clearance and factory gauge compatibility.
Streamlined Installation with Factory Ready Bracket
The kit's mounting bracket aligns precisely with existing frame rail holes beneath the rear axle, eliminating the need for drilling or adapter components. By using factory hardware locations it secures the tank assembly directly to original points on GM 1991 to 2005 chassis conversions. This approach preserves bed space and maintains the vehicle's center of gravity for uninhibited handling. Installers benefit from a drop in fit that reduces labor time and minimizes fitment errors. The rigid support also shields the tank and fittings from road debris and lateral forces encountered during cornering while preserving clearance from suspension and heat sources.
Advanced Internal Baffling for Uninterrupted Fuel Flow
Within the eighteen gallon tank a multi chamber baffling system directs fuel to the inlet even under steep braking or sharp cornering. The partitions prevent air pockets from forming around the Walbro pump, ensuring full immersion and consistent pressure delivery. Drivers will avoid lean spikes and erratic fuel pressure that can trigger ECU fault codes or cause hesitation. The integrated design requires no additional modifications and maintains tank integrity. This internal arrangement provides steady supply during both regular cruise and sudden throttle changes, supporting reliable performance under demanding conditions.
Walbro 400 LPH Pump Delivering Steady Performance
Central to the kit is a Walbro pump rated for 400 liters per hour, capable of supporting LS engines up to 750 horsepower. Precision machined internal components minimize pressure drop across the system and reduce heat generation during sustained high load operation. This stability prevents vapor lock and cavitation that can compromise fuel delivery and engine response. By maintaining consistent flow under varying throttle positions the pump simplifies fuel system tuning and ensures the ECU receives accurate commands. The robust design meets the demands of both spirited street use and track duty.
OEM Grade Sending Unit for Accurate Fuel Level Monitoring
The included sending unit offers a zero to ninety ohm resistance profile that matches the factory gauge circuitry used in GM models from 1991 to 2005. This direct compatibility avoids complex harness adapters and retains original dash cluster behavior without recalibration. Its bolt pattern mirrors the factory unit, allowing a seamless swap with no new mounting holes or seal modifications. Calibration across the full eighteen gallon capacity ensures drivers experience precise level readings and predictable fuel range. The result is a straightforward upgrade that preserves classic instrument function.
Engineered to integrate seamlessly with GM chassis conversions the kit ensures precise fitment reliable fuel delivery and durable performance for your LS swap.
