1974-1977 Chevrolet Vega EFI Fuel Tank Kit with 400 LPH Pump
Converting a 1974-1977 Chevrolet Vega to electronic fuel injection often exposes the stock tank as a weak link, and this Vega EFI Fuel Tank Kit with 400 LPH Pump delivers both the capacity and flow required to support up to 750 horsepower setups. Its galvanized steel construction coated in a silver finish resists corrosion and retains the original 19 gallon profile, so no custom brackets or frame modifications are needed. Featuring a 400 LPH Walbro pump within the tank module, this kit maintains stable pressure under high load and preserves trunk clearance for authentic Vega appearance. Installation aligns with factory mounting points and uses the OE filler neck, straps and sending unit connections to streamline the conversion process.
Precision Direct Fit Installation for 1974 to 1977 Vega Models
This fuel tank kit is engineered to match the exact footprint of the original Vega unit, aligning with factory mounting rails and body supports without modification. By preserving the stock tank profile and using the OE filler neck, straps and sending unit connections, installers can complete the conversion with minimal fabrication work. Plug and play integration of the in-tank module and pump connections reduces the number of potential leak points and expedites the process for both professionals and home enthusiasts. The precise mounting alignment not only saves time but also maintains the structural integrity of the chassis, ensuring consistent support under dynamic driving loads and preserving the classic underbody configuration.
Galvanized Steel Tank with Durable Silver Finish
Constructed from heavy gauge galvanized steel, the tank offers remarkable resistance to corrosion from road debris, moisture and fuel vapors. The silver finish, applied through a multi stage powder coat process, creates a tough barrier against scratches and environmental wear, prolonging service life even in harsh conditions. This protective layer also retains its appearance without frequent touch ups, so the underbody keeps its authentic look over time. Choosing coated steel ensures that the tank can withstand thermal cycling and resist pitting, which is critical when supporting higher pressure fuel pumps and ethanol blends commonly used in performance applications.
400 LPH Walbro Pump Ensuring Stable Flow Under Load
At the heart of this kit is a 400 LPH Walbro fuel pump capable of delivering consistent fuel flow to engines rated up to 750 horsepower. Its in-tank placement pushes fuel toward the engine inlet, reducing the risk of vapor lock and cavitation that can occur with external feed systems. This design maintains a steady supply during hard acceleration, steep inclines and track use, preventing lean spikes that threaten engine health. The high capacity output supports sustained high rpm operation without pressure drop, giving drivers the confidence that their powertrain will receive the precise volume needed for peak performance.
Comprehensive Kit Components for Streamlined EFI Conversion
This all inclusive kit brings together every element required to upgrade from carburetion to fuel injection: the 400 LPH Walbro pump, in-tank pump module, sending unit, filler neck, tank straps, vent filter, gaskets and mounting hardware. Each part has been selected to mirror the original equipment form and function, eliminating the hassle of sourcing compatible accessories. The integrated vent filter maintains proper tank ventilation under varying pressures, while the precision sentry unit ensures accurate level readings on the factory gauge. By supplying all critical components, this kit simplifies logistics and supports a clean installation that performs as reliably as the factory setup.
