340 LPH LS Fuel Tank Pump and Fitting Kit for GM Models
When swapping an LS engine into a 1991 to 2005 GM chassis, uninterrupted fuel supply can make or break the build and this 340 LPH Fuel Pump and Fitting Kit stands ready to maintain steady flow. Combining a 340 liter per hour Walbro pump with precision machined adapters and corrosion resistant fittings, the assembly keeps pressure consistent under sharp acceleration, hard braking, and tight turns. Installation requires no tank modifications thanks to application specific hardware that mates directly with factory lines for seamless in tank or frame mount setups. Internal baffling holds fuel around the pickup inlet to prevent cavitation while a calibrated zero to thirty ohm sending unit delivers accurate gauge readings.
Precision Internal Baffle System Prevents Fuel Starvation
The internal baffle system divides the tank into separate chambers that keep fuel around the pickup inlet even under abrupt deceleration or tight cornering. By preventing fuel slosh away from the inlet, the design maintains constant pump inlet pressure and avoids cavitation. This preserves pump life and extends service intervals by ensuring the unit remains submerged at all times. Consistent inlet coverage means predictable throttle response during aggressive maneuvers, eliminating hesitation or surge. The baffling also minimizes air ingestion that can compromise combustion. Together, these measures deliver uninterrupted engine output across varied driving conditions.
In-Tank 340 LPH Walbro Pump and Thermal Management
Placing the Walbro pump inside the fuel tank lets it draw cooling directly from the surrounding fuel, controlling operating temperature and preventing overheating during sustained use. The 340 liter per hour flow rate supports engines making up to 750 horsepower while avoiding undue stress on the unit. Integrating the pump eliminates external feed lines, reducing potential leak points and simplifying under chassis routing. Noise and vibration are damped by the fuel medium, resulting in quieter operation. Precision machined adapters ensure a direct fit to factory lines for a clean installation. This arrangement improves long term reliability by shielding the pump from debris and harsh environments.
Zero to Thirty Ohm Sending Unit for Accurate Gauge Readings
The sending unit is calibrated to report fuel level across a zero to thirty ohm range that matches original GM gauges, so no additional calibration or wiring changes are required. Its linear response maintains smooth, predictable movement of the dash needle as fuel volume changes. Standard connector interfaces allow it to plug directly into an existing LS engine harness without splicing or adapter cables. Mounting the unit in the tank retains original venting and pressure characteristics needed for modern EFI systems. Accurate level readings at all driving angles help avoid unexpected stops on long trips. This approach preserves classic dash functionality while supporting contemporary injection requirements.
Eighteen Gallon Tank Capacity and Seamless Chassis Integration
With an eighteen gallon capacity, the fuel tank extends driving range and reduces the frequency of refueling stops on long journeys or spirited outings. The shape and size are tailored to fit neatly between frame rails on 1991 through 2005 GM platforms, preserving ride height and ground clearance. A factory matched bed filler neck maintains original refueling ergonomics, making installation as simple as dropping in the tank and connecting to stock fuel lines. Positioning weight low in the chassis enhances vehicle balance and cornering stability. The precision machined mounting flange aligns with existing holes, eliminating the need for trimming or custom brackets. This blend of volume and fitment streamlines LS engine swap projects without compromise.
Engineered for consistent fuel delivery and straightforward installation in LS swap applications.
