1966-1967 Chevy II/Nova X-Body LS EFI Fuel Tank Kit with 400 LPH Pump
When embarking on an LS engine swap into a 1966 to 1967 Chevy II or Nova chassis, reliable fuel delivery becomes a top priority. The 1966 to 1967 Chevy II EFI Fuel Tank Kit with a 400 LPH pump provides a complete EFI solution with a 400 liter per hour electric pump rated to feed over 550 hp and an in-tank module that integrates a precision fuel level sending unit. Engineered as a direct replacement EFI fuel tank for Chevy II X Body models, the kit arrives with tank straps, a filler neck, vent filter, gaskets and all mounting hardware to ensure perfect fitment. Its stamped steel shell matches factory undercarriage contours for straightforward installation.
Engine Compatibility and Precision Fitment
The 1966 to 1967 Chevy II EFI Fuel Tank Kit with 400 LPH Pump is engineered exclusively for first generation Chevy II X Body models. This focused design ensures seamless integration when performing an LS engine swap, maintaining the factory frame clearances and suspension geometry. By pairing the tank and pump assembly with MuscleRods mounts, installers gain confidence in precise engine placement and correct drivetrain angles. This synergy reduces stress on transmission linkages, lowers vibration levels and preserves chassis integrity for both daily driving and track duty.
Pump Performance and Reliable Fuel Delivery
At the heart of this kit lies a 400 LPH Walbro electric fuel pump capable of supporting more than 550 hp applications. Housed within a fully sealed in-tank module, the pump delivers consistent pressure under high demand scenarios, preventing lean-condition risks during hard acceleration or steep grades. The integrated precision fuel-level sending unit supplies accurate data to the gauge cluster, eliminating guesswork and allowing the driver to monitor fuel status in real time. This cohesive solution ensures smooth fuel flow to the LS engine's injectors, optimizing throttle response and power delivery across the entire rev range.
Robust Construction and Extended Range
Every component of this EFI fuel tank kit is built from durable materials selected for endurance in demanding environments. The corrosion-resistant tank shell and heavy-duty fittings stand up to road debris, chemical exposure and vibration cycles without compromise. By increasing the stock fuel capacity, the kit extends driving range, reducing refueling stops during long cruises or competitive endurance events. The sturdy design also simplifies future maintenance, as the module can be removed and serviced without altering the vehicle's original fuel lines or chassis mounts.
