1968-1970 Chevy El Camino LS and LT EFI Fuel Tank Kit with 400 LPH Pump
If you are fitting an LS or LT powerplant into a 1968 to 1970 A Body El Camino this EFI fuel tank kit solves the fuel delivery challenge by matching original stock mounting points and contours for a straight bolt in installation. Replicating factory tabs and ports means the tank integrates cleanly with existing fuel lines and maintains ground clearance and underbody profile. It uses a 400 LPH Walbro pump to sustain flow under hard acceleration and guard against lean conditions when demand spikes and has enough capacity to support engines making over 550 hp without requiring an auxiliary unit. The combined pump module, sending unit and hardware arrive as a single assembly to streamline plumbing and wiring and reduce installation time.
Exact Fitment to 1968 to 1970 El Camino Undercarriage
This fuel tank is engineered to match the original 1968 to 1970 Chevy El Camino underbody profile, replicating factory mounting tabs and port locations for a genuine bolt-in solution. By mirroring the stock geometry, installers avoid cutting, drilling or welding, preserving the integrity of the A-Body frame and maintaining the vehicle's designed ground clearance. Accurate alignment of vent fittings and pump ports reduces stress on seals and hoses, lowering the risk of leaks or premature wear over time. The precise contouring also ensures even support across the tank shell, preventing deformation or rattling once the assembly is secured. Enthusiasts will note how this exact fit accelerates the overall swap process and keeps first-time EFI installers confident in the outcome.
400 LPH Pump Sustaining Over 550 HP Engine Output
At the heart of this fuel system sits a Walbro 400 LPH pump designed to serve supercharged or high-output LS and LT powerplants exceeding 550 hp. Delivering a steady and uniform flow under rapid throttle changes, it safeguards against lean conditions that could otherwise lead to detonation or engine damage. The robust volume reserve accommodates future upgrades such as larger injectors or forced induction without the need for a secondary pump. Uniform pressure output also sharpens injector response, allowing the ECU to maintain precise control of air-fuel ratios during hard launches and sustained high-RPM runs. This built-in capacity gives builders peace of mind that fuel delivery will stay ahead of demand, even under track or street performance use.
Unified Module Streamlining Plumbing and Electrical Connections
Rather than sourcing individual parts, this kit combines the pump, sending unit, vent filter, gaskets and mounting hardware into a single assembly that greatly simplifies the installation flow. Grouped electrical connectors and dedicated plumbing fittings cut down on separate harness runs and hose assemblies, minimizing potential leak paths and wiring errors. Preselected gaskets and straps ensure a consistent seal against fuel vapor and moisture intrusion, while the integrated filler neck and vent filter speed up line routing. By delivering a ready-to-install unit, the design reduces build time, eliminates missing parts and delivers a clean, organized underbody layout. Installers gain a more straightforward process and a tidier final result with fewer adjustments or substitutions required.
Corrosion-Resistant Steel Tank with Fuel Slosh Control
Constructed from high-grade steel and finished to resist corrosion, this tank is assembled with precision welded seams at critical stress points to ensure long-term integrity. Internal baffling around the pump module dampens fuel movement during hard launches, cornering or uneven surfaces, guaranteeing uninterrupted pickup and preventing pump cavitation. The durable coating stands up to road debris and chemicals, safeguarding the metal shell from pitting and rust over countless miles. Even though the tank sits unseen beneath the bed, its modern engineering blends seamlessly with classic styling, maintaining the El Camino's iconic appearance. By combining rugged materials with thoughtful internal design, the assembly delivers dependable fuel delivery under all driving conditions.
