1966-1967 X-Body LS Fuel Delivery Upgrade with 400 LPH Pump

Robust steel construction provides factory-precision fit for 1966 to 1967 Chevy II X Body models, integrating a 400 LPH Walbro electric fuel pump and tank module to deliver consistent high volume fuel flow for engines over 550 hp. Combined with a precision fuel level sending unit, increased capacity and durable materials, this kit ensures accurate readings under harsh conditions, seamless integration into LS swaps and extended driving range without sacrificing reliability.

LS EFI Fuel Tank Kit with 400 LPH Pump for 1966-1967 Chevy II/Nova

Installing an LS powerplant in a 1966 and 1967 Chevy II X-Body places extra demand on the stock fuel reservoir; this 1966-1967 Chevy II EFI Fuel Tank Kit - 400 LPH Pump replaces the original with a tank mounted Walbro module that sustains flow for engines over 550 horsepower. Its contour matched steel shell mounts with factory straps to maintain ground clearance. The precision fuel level sender links directly to modern EFI systems for accurate readings from the start. Surrounding fuel cools the submerged pump during spirited driving to reduce vapor lock risk and ensure steady delivery.

Precision Fitment for 1966 1967 Chevy II X Body

The fuel tank kit's shell is stamped from heavy gauge steel to match the factory contours of 1966 and 1967 Chevy II X Body models. By using the original mounting points and factory straps you retain ground clearance and preserve the vehicle’s classic profile without any chassis alteration. This exact match fit reduces installation complexity and eliminates alignment issues that can arise from custom fabrication. The tank also features a corrosion resistant finish that stands up to modern ethanol blends and harsh road conditions. Its increased internal volume adds reserve capacity for long drives and track days.

Submerged Pump Cooling for Consistent Flow

Positioning the 400 LPH Walbro electric pump inside the fuel volume allows the surrounding gasoline to act as a heat sink during extended high rpm operation. This immersion cooling effect lowers pump temperature and prevents vapor lock under demanding driving or hot ambient conditions. The Walbro unit is calibrated to sustain flow rates for engines north of 550 horsepower and features robust internal components to resist wear. Low vibration mounts help keep noise levels down while protecting the pump housing from fatigue. Together these measures deliver an uninterrupted fuel supply when it matters most.

Integrated Fuel Level Sender for Modern EFI Calibration

The built in precision fuel level sender interfaces directly with contemporary electronic fuel injection systems, eliminating the need for adapter harnesses or custom sender housings. Calibration is achieved at the factory so readings are accurate from the first ignition cycle, giving real time data to your engine control module and dashboard gauge. This direct communication improves driveability by ensuring the fuel gauge remains reliable under all operating conditions. Service technicians also appreciate the plug and play design when diagnosing fuel level concerns. The unit's sealed connectors resist moisture intrusion and maintain signal integrity over thousands of miles.

Comprehensive Kit Components for Streamlined Installation

Every element required for the upgrade arrives in one package, including the high volume pump module, sending unit, tank straps, filler neck, vent filter, gaskets, and mounting hardware. A detailed instruction guide walks through tank removal and new assembly installation using existing mounting brackets and crossmember clearances. No additional brackets or specialty tools are needed, which shortens labor time and keeps installation costs in check. This all inclusive approach simplifies the swap even for enthusiasts new to frame mount fuel systems. The ready to install kit lets you focus on finishing your LS engine build without chasing missing parts.

Count on unwavering fuel delivery. To complement your setup consider our 1966-1967 Chevy II EFI Fuel Tank Kit - 255 LPH Pump as a Smaller capacity fuel pump Kit at 255 LPH.
