1974-1977 Chevrolet Vega EFI Fuel Tank Kit with 400 LPH Pump
Upgrading a 1974-1977 Chevrolet Vega to fuel injection often leaves the stock tank struggling to keep pace and this EFI Fuel Tank Kit offers a ready to install solution. Built from galvanized steel in the original 19 gallon profile, it fits directly in place of the factory unit without the need for custom brackets or frame alterations. Featuring a 400 LPH Walbro pump housed within the tank module, it sustains steady flow for setups up to 750 horsepower under hard acceleration and heavy load. By using the OE filler neck, straps and sending unit connections the kit preserves trunk clearance and classic Vega lines while delivering consistent fuel delivery for confident driving.
Precision Direct Fit Installation for 1974 to 1977 Vega Models
This fuel tank kit is engineered to align exactly with the original Vega mounting points, using the factory rails and body supports to ensure a seamless swap. By retaining the OE filler neck, straps and sending unit connections, the installation avoids welding or bracket fabrication, preserving chassis integrity and underbody structure. The in tank module slides into place without modification to the frame, cutting install time and reducing the risk of misalignment. Maintaining the stock tank profile also ensures trunk clearance remains unchanged, so the classic lines of the Vega are preserved even after upgrading to modern injection. This precise fit approach benefits both professional mechanics and home builders by delivering a straightforward, dependable solution that maintains the vehicle's original support geometry.
Galvanized Steel Tank with Durable Powder Coat Finish
Constructed from heavy gauge galvanized steel, this tank offers exceptional resistance to corrosion from moisture, road debris and ethanol blends. A multi stage silver powder coat finish forms a robust barrier against scratching and environmental wear, extending the service life in harsh conditions. This protective layer helps prevent pitting and rust formation, which can compromise fuel quality and system pressure over time. The coated steel also stands up to thermal stress during hot and cold cycles without cracking or peeling, ensuring the original 19 gallon capacity remains dependable. By combining proven materials with advanced coating technology, the design delivers lasting protection while preserving the authentic underbody appearance of the classic Vega.
400 LPH Walbro Pump for Reliable Fuel Delivery
At the heart of this kit is a 400 LPH Walbro fuel pump capable of supplying enough fuel for engines rated up to 750 horsepower without pressure drop. Its placement inside the tank forces fuel toward the outlet port, which minimizes the risk of vapor lock and cavitation during hard acceleration or steep grades. This in tank setup maintains consistent flow under cornering and heavy load, preventing lean conditions that could harm engine components. By delivering a stable volume at all times, the pump supports smooth throttle response and sustained high rpm operation. Drivers benefit from precise fuel metering that ensures performance demands are met with confidence on both street and track.
