1964-1967 Chevy Chevelle LS EFI Fuel Tank Kit with 255 LPH Pump
Swapping an LS engine into a Chevelle built between 1964 through 1967 exposes the original fuel system's limits under sustained throttle and spirited driving conditions. This EFI Fuel Tank Kit for 1964 through 1967 Chevelles integrates a 255 LPH pump module directly inside the tank to fit factory mounting points without fabrication while keeping fuel cool and vapor lock at bay. Complete hardware including straps, gaskets and a vent filter streamlines assembly and keeps the stock tank bay intact. A precision calibrated sending unit matches the factory resistance curve to deliver accurate gauge readings on lengthy drives or track laps.
Submerged Walbro Pump Ensuring Stable Fuel Delivery
The in-tank Walbro module sits fully immersed in fuel, leveraging the surrounding liquid to cool its internal components and prevent heat soak. Rated at 255 LPH, it meets the demands of engines producing up to 550 horsepower while maintaining consistent output under heavy throttle. By operating below the liquid surface, the pump minimizes vapor lock risk and reduces thermal stress that can shorten service life. This design also retains factory routing and clearance beneath the chassis, so no additional brackets or body modifications are required. As a result, fuel pressure remains rock steady during spirited acceleration or highway cruising, delivering dependable performance every time you drive.
Factory Style Installation Preserving Original Tank Bay
This EFI kit drops directly into the original tank bay without any cutting or welding, preserving the structural integrity of the frame rails and sheet metal contours. Mounting points line up precisely with the stock positions, allowing you to reuse the factory straps, body holes, and filler neck opening for a seamless fit. The vent filter and gasket locations also match the factory layout, ensuring that emissions venting and sealing remain OEM compliant. By eliminating fabrication and custom brackets, installation time is greatly reduced and assembly error potential is lowered. The outcome is a clean underbody appearance that maintains the classic look of your 1964 through 1967 Chevelle.
Precision Sending Unit Matching OEM Gauge Performance
The calibrated sending unit replicates the factory resistance curve to deliver accurate fuel level readings through the original gauge cluster. Its corrosion resistant float arm and durable wiring harness maintain smooth electrical connectivity over years of operation, preventing erratic or false empty warnings. Because the output mirrors stock behavior, drivers can trust remaining range estimates during long drives or track sessions without second guessing gauge swings. This linear response also helps in planning timely refueling stops, avoiding surprises at service stations and reducing downtime. Proper meter feedback is essential when operating an LS swap at sustained loads, making this sender a critical component.
All Inclusive Hardware Package Streamlining Assembly
Everything required for a professional quality conversion is included in this kit: the 255 LPH Walbro pump, internal module, sending unit, tank straps, filler neck, vent filter, gaskets, fittings, and fasteners. Clear, step by step instructions outline correct gasket placement and specify torque values to achieve a leak free seal. Builders save hours of parts hunting by relying on components engineered to work together, eliminating mismatches and compatibility headaches. The unified hardware package also reduces the chance of installation errors or costly callbacks, as every fitting is matched to the Chevelle fuel bay. With this comprehensive set, upgrading to reliable EFI becomes a straightforward process rather than a scavenger hunt for parts.
