In Tank Walbro 400 LPH Pump Performance
At the core of the system is a Walbro pump rated at 400 liters per hour to support LS or LT engines up to and beyond 550 horsepower. Installed directly into the fuel reservoir the pump remains submerged to avoid vapor lock during hard acceleration or track sessions. This submerged location also helps reduce turbulence and ensures consistent flow under high demand. Whether the engine is naturally aspirated or uses boost the result is stable fuel pressure for reliable operation.
Calibrated Sender Integration with OEM Wiring
The precision sender arm is shaped to follow the internal contours of the Skylark tank and eliminate blind spots that cause false readings. It connects directly to the factory gauge harness with no splices or adapters so the dash layout remains unaltered. Calibration of the sender matches the tank s full range for more accurate level readings from empty to full. This plug and play design lets drivers monitor fuel status with confidence on every journey.
American Made Installation Components Streamline Assembly
Every gasket strap and vent filter in this kit is fabricated in the United States to meet strict quality standards. OEM style tank straps align precisely with the frame for secure support and quick retention of the conversion tank. High quality molded gaskets resist fuel seepage under pressure and temperature extremes while the period correct vent filter prevents debris entry. By including all necessary hardware installers can complete the conversion without extra trips for missing parts.
