1966-1967 Chevy II/Nova EFI Fuel Tank Kit with 255 LPH Pump for LS Swap
The 1966 or 1967 Chevy II EFI Fuel Tank Kit with 255 LPH Pump ensures consistent fuel pressure under demanding conditions when installing an LS engine in a Chevy II or Nova X Body. It integrates a Walbro unit inside a reproduction tank shell and uses factory mounting points to avoid any floor modifications while preserving original body lines. Installation remains straightforward thanks to preassembled components and gaskets cut to exact specifications and the in tank pump location delivers cool operation, low noise and steady flow to support up to 550 horsepower.
Submerged Fuel Pump for Efficient Cooling and Quiet Operation
Positioning the 255 liter per hour Walbro pump inside the tank ensures it remains fully submerged, which draws heat away from the motor and extends service life. Submersion also acts as a natural silencer, reducing hum and buzz compared with external mounting designs. With the pump wrapped in fuel, internal temperatures stay lower and components face less wear, even under sustained high demand. The gradual flow of liquid around the motor quiets moving parts, so drivers experience a more refined sound profile at idle and during rapid throttle transitions. This arrangement supports reliable operation in both hot summer runs and long highway cruises.
Tailored Fit for 1966 or 1967 Chevy II and Nova X Body Frames
This kit makes use of existing factory mounting locations on the Chevy II and Nova X Body underbodies, so no alteration to the floor pan is required. Sealing gaskets are precision cut to match original tank openings, creating a leak proof seal that preserves the classic underbody silhouette. Exhaust and suspension systems remain unaffected thanks to the exact contour match, eliminating interference or rubbing concerns. Installers benefit from a design that aligns with original chassis specifications and maintains the car's period correct appearance. Body lines and ground clearance stay true to the vintage profile.
Integrated Module for Streamlined Assembly and Leak Prevention
The complete fuel module arrives fully assembled with pump, sending unit, filler neck and vent filter preinstalled, dramatically reducing installation time and potential error points. By housing critical components in a single, rigid frame, the design minimizes the number of gaskets and loose parts that can develop leaks. The included sending unit follows the stock gauge curve for accurate readings while the vent filter protects against moisture and debris intrusion. Clear instructions guide installers through a few straightforward steps, cutting out the need for custom brackets or additional fabrication.
Consistent High Volume Supply for LS Engine Builds
Delivering up to 255 liters of fuel per hour, this pump supports LS engine outputs as high as 550 horsepower without risk of starvation under hard acceleration. Steady pressure eliminates fluctuations that can cause hesitation or lean conditions, ensuring clean combustion and optimal injector performance. Improved throttle response and more precise fuel metering translate into crisper acceleration and better fuel economy in varying driving scenarios. Whether carving twisty back roads or cruising on the freeway, drivers can count on consistent supply to match the demands of a modern EFI powerplant.
This fuel tank solution delivers steady performance under sustained acceleration. For a Larger capacity fuel pump Kit at 400 LPH see our 1966-1967 Chevy II EFI Fuel Tank Kit - 400 LPH Pump.
