1968-1970 Chevy El Camino LS EFI Fuel Tank Kit with 255 LPH Pump
If space constraints under the frame rails and steady fuel delivery are top concerns in a classic El Camino build, this 1968-1970 El Camino EFI Fuel Tank Kit is engineered to address both by pairing a notched steel tank with a 255 LPH Walbro pump. It features precision matched contours that clear wider tires and exhaust piping without requiring any chassis trimming. By submerging the pump within the tank, fuel stays cooler and pressure remains consistent during rapid throttle shifts on LS engines up to 550 horsepower. Complete with a sending unit, straps, gaskets, and a filler neck, the kit guides novice installers through a straightforward setup while maintaining factory fuel level accuracy under load.
Optimized Notched Tank Contours for Exhaust and Tire Clearance
The notched layout of this fuel tank is precision formed to match the lower frame rails of the classic El Camino, creating vital space around wider tires and exhaust tubing without any chassis cutting. By following the original profile of the A Body rails, the tank avoids contact during suspension travel and maintains factory ground clearance under all driving conditions. Strategic shaping along the notches also promotes better heat dispersion from the exhaust system, reducing radiant heat transfer to stored fuel. Installers appreciate that no trimming or grinding on the vehicle frame is required, preserving the structure and finish of the undercarriage. In spirited driving or towing, this design ensures there are no interference points or unwanted noise from rubbing components.
Submerged Pump Placement for Consistent Fuel Delivery
At the core of this module sits a 255 LPH Walbro pump fully immersed in fuel, a configuration that keeps the unit running cooler and more quietly than external setups. Submersion prevents vapor lock during hard acceleration or sustained high rpm use, safeguarding against fuel starvation in performance applications up to 550 hp. With the pump mounted directly in the tank, line length is minimized and pressure remains stable through rapid throttle transitions, which translates to sharp engine response and reliable horsepower output. This arrangement also simplifies plumbing routes and reduces the number of external fittings, cutting down potential leak points. Overall, you gain steady flow under load and extended service life for the pump.
Integrated Kit Components Streamline Installation Process
This all in one assembly brings together the fuel pump module, sending unit, straps, filler neck, vent filter, gaskets and mounting hardware in a single package. Detailed instructions guide you through preparing the frame pocket, aligning components, and performing leak checks so even those new to engine swaps can achieve a professional result. The sending unit is calibrated to maintain factory level accuracy under all load conditions, eliminating guesswork in dialling in fuel gauge readings. Once the module is set in place, straps tighten securely to the existing mounting points, and the filler neck snaps into the original inboard opening. By integrating every essential part, the kit removes fitment hassles and keeps the installation on schedule.
