LS and LT EFI Fuel Tank Kit for 1968-1970 Chevy El Camino
The 1968-1970 El Camino EFI Fuel Tank Kit - 400 LPH Pump addresses the challenges of installing an LS or LT engine into a classic A Body frame by delivering precise fit and reliable flow. Custom fitting is removed thanks to the tank's faithful replication of original mounting points and contours which allow a bolt in installation without any cutting or welding. A built-in 400 LPH Walbro pump ensures consistent fuel volume for engines producing over 550 hp and guards against lean conditions under rapid throttle changes. This complete assembly also streamlines plumbing and wiring by combining the pump module, sending unit and mounting hardware into a single ready to install unit.
Optimized Fuel Flow for Over 550 HP LS and LT Engines
The heart of this EFI fuel tank kit is a 400 LPH Walbro pump engineered to deliver a steady stream of fuel under extreme demand from supercharged or naturally aspirated LS and LT powerplants. By sustaining consistent volume, the assembly prevents lean conditions that can lead to detonation and component wear during full-throttle acceleration. Uniform pressure output also sharpens throttle response, allowing each injection event to match ECU commands without delay. Enthusiasts planning to increase injector size or add nitrous benefit from built-in capacity reserve, avoiding an extra pump upgrade down the road. This margin keeps your fuel system ready for power increases without compromising drivability or reliability.
Exact Replica of Original A Body Tank Profile
This fuel tank mirrors the shape, mounting tabs and port locations of the stock 1968–1970 El Camino unit so installers enjoy a true bolt-in replacement. No trimming, drilling or welding is required; simply drop the tank into the A Body frame and secure it to factory studs. Accurate alignment of vent fittings and pump ports reduces stress on seals and hoses, minimizing the chance of leaks or vibration-related failures. Maintaining original ground clearance ensures the vehicle's underbody aesthetics and handling characteristics remain unchanged. Even first-time EFI converters appreciate how this precise fit streamlines the integration of modern fuel delivery into a classic chassis.
Integrated Pump Module Streamlines Wiring and Plumbing
This kit combines the pump, sending unit, vent filter, gaskets and mounting hardware into one cohesive module that greatly simplifies installation. Grouped electrical connectors and plumbing fittings cut down on separate harnesses and hose runs, reducing potential leak paths and wiring errors. Preselected gaskets and straps ensure a reliable seal against fuel vapor and moisture intrusion, while quick-connect vent components speed line routing. By eliminating the need to source individual parts, the assembly shortens build time and prevents frustrating delays. The result is a clean underbody layout that keeps wiring tidy and fuel lines organized.
Robust Assembly Designed for Enduring Service
Constructed from corrosion-resistant steel and precision-welded at critical seams, this tank is built to withstand years of duty without metal fatigue or failure. Internal baffling around the pump module reduces fuel slosh and maintains pickup during hard launches or cornering, ensuring uninterrupted feed to your engine. A durable finish resists chemicals and road debris, preserving the unit's integrity under the vehicle. Even unseen beneath the bed, the tank's modern contours blend seamlessly with the El Camino's stock silhouette. Through meticulous engineering and quality manufacturing, this assembly delivers reliable fueling performance mile after mile.
