1968-1970 Chevy El Camino EFI Fuel Tank Kit for LS Swap
If you are fitting an LS engine into a 1968 to 1970 El Camino chassis this EFI fuel tank kit addresses both space and flow challenges by combining a notched contour with a 255 LPH Walbro pump designed to fit within the factory frame rails. It clears wider tires and exhaust runouts without chassis trimming by following the original A Body rail profile and promoting cooler fuel temperatures through submersion of the pump within the steel tank. Complete with a calibrated sending unit, mounting straps, gaskets and a filler neck this assembly ensures accurate fuel level readings under load and guides enthusiasts through a straightforward DIY install.
Precision Notched Tank for Chassis Clearance
The notched contour of this fuel tank is precision formed to match the frame rails of a 1968 to 1970 El Camino, creating vital space for wider tires and exhaust routing without altering the chassis. By tracing the original A-Body rail profile, the tank maintains factory ground clearance and eliminates interference during suspension travel. This tailored approach preserves the vehicle's structural integrity and prevents unwanted noise or wear from rubbing components. Installers benefit from a plug-and-play fit that removes the need for any trimming or fabrication, keeping both time and restoration cost to a minimum.
Submerged Pump Placement for Stable Fuel Supply
At the heart of this assembly lies a 255 LPH Walbro pump installed directly inside the tank, ensuring steady fuel flow under all driving conditions. Immersion in fuel helps the pump run cooler and more quietly than external setups, while keeping line length short and pressure consistent during rapid throttle changes. This configuration also eliminates the risk of vapor lock in performance driving, supporting engines up to 550 hp without interruption. Fewer external fittings mean fewer potential leak points, yielding a cleaner installation and greater reliability at sustained high rpm.
Calibrated Sending Unit and Streamlined Installation
This kit includes a sending unit pre-calibrated for the El Camino fuel gauge, delivering precise level readings under load and during spirited acceleration. Comprehensive instructions walk you through preparing the frame pocket, aligning the pump module, verifying seals, and completing leak checks. Once the unit is seated, heavyduty straps secure it to existing mounts and the filler neck snaps into the factory opening, guiding even first-time installers to a professional outcome. Clear documentation and included gaskets eliminate guesswork and help keep the project on schedule.
Robust Steel Tank Construction with Heat Management
Constructed from high-grade steel, the tank resists flexing and stress over time, providing a stable base for the in-tank components. Strategic shaping along the notches promotes better heat dispersion from nearby exhaust tubing, reducing radiant transfer to stored fuel and helping maintain cooler temperatures. The durable finish retards corrosion, extending service life in varied conditions. Together, these design choices ensure that both pump and fuel remain protected, delivering consistent performance throughout every drive.
