1971-1972 Chevy El Camino LS and LT EFI Fuel Tank Kit with 400 LPH Pump
When converting a 1971-1972 Chevy El Camino to LS or LT power the stock tank often falls short under heavy throttle applications. This EFI fuel tank kit delivers ample flow for engines up to 550 hp while bolting directly to original underbody rails using factory bracket locations so no cutting or welding is needed. By matching the tank filler neck straps and gaskets to the factory points installation is a straightforward process. Crafted from thick gauge steel with internal baffles and a precision vent filter the assembly maintains consistent pressure and prevents fuel slosh during spirited street runs or track sessions.
Seamless Integration with Factory Mounts
This EFI fuel tank kit installs directly onto the existing underbody rails of 1971 to 1972 El Camino A Body chassis without any cutting or welding. By matching the original bracket locations for the tank, filler neck, straps and gaskets, it preserves the factory framework and maintains chassis rigidity. Precise dimensional accuracy eliminates guesswork during installation and keeps the undercarriage layout clean, allowing exhaust and suspension components to fit without conflict. Even first time installers will appreciate the clear alignment cues that reduce assembly time and ensure a professional result on every build.
400 LPH Walbro Pump Ensuring Steady Fuel Delivery
At the core of this kit is a 400 LPH Walbro pump designed to support engines making up to 550 horsepower, including supercharged setups. Its high capacity flow curve prevents fuel pressure from dropping under heavy throttle or rapid load changes, guarding against cavitation and lean conditions. Because the pump resides inside the tank, it benefits from continuous fuel cooling and reduced noise compared to external units. This in-tank design also simplifies plumbing and wiring, delivering sharper throttle response and consistent performance on both street and track.
Robust Steel Tank and Internal Baffle Management
The tank body is formed from thick gauge steel with corrosion resistant treatment to withstand road moisture, salt and temperature extremes. Internal baffles are strategically placed to control fuel motion during hard cornering, sudden stops or uneven pavement, ensuring the pump pickup remains submerged and avoiding starvation. This stable environment prevents hesitation when tank levels are low and extends component life by reducing vibration. Heavy duty straps and mounting hardware secure the assembly firmly, promoting chassis stability and a quiet underbody.
Precision Venting and Reliable Level Sensing
A dedicated vent filter assembly maintains balanced internal pressure by allowing air to reenter the tank while blocking contaminants, preventing vacuum lock as the pump draws fuel. The integrated sending unit delivers accurate fuel level readings to the gauge, so drivers can plan refueling stops with confidence whether on a daily commute or spirited backroad run. Both components arrive preassembled in the pump module, streamlining installation and minimizing wiring complexity. The result is a clean undercarriage finish with no loose parts and reliable system operation in all conditions.
