EFI Fuel Tank Kit with 255 LPH Pump for LS Swapped 1965-1967 Pontiac GTO
When installing an LS engine in a 1965 to 1967 Pontiac GTO A Body chassis, maintaining consistent fuel pressure during hard cornering or sudden throttle changes is crucial. This EFI Fuel Tank Kit integrates a 255 LPH pump into an OEM reservoir and secures with factory mount points for a clean fit without alterations. Internal baffling keeps the module submerged to prevent air pockets and safeguard EFI operation under high demand. The calibrated sending unit mirrors factory gauge resistance for accurate level readings without extra adapters.
Direct Fit Chassis Alignment Using Factory Mount Points
By utilizing original A-Body fuel tank attachment points this kit installs seamlessly without cutting or welding the undercarriage. Precision molded pads align the reservoir accurately against factory rails and crossmembers, preserving the chassis geometry designed by Pontiac engineers. Included straps and gaskets replicate OE hardware to form a leak-resistant seal that endures both spirited acceleration and daily driving. Eliminating fitment guesswork not only reduces shop hours but also maintains vehicle safety by keeping the tank firmly in place under all conditions. This true plug-and-play solution lets installers focus on system integration rather than fabrication.
Engineered Slosh Control for Uninterrupted Pump Intake
Internal baffles in the tank are strategically placed to trap fuel around the inlet area during sharp turns, sudden stops, and hard launches. This slosh control design prevents air pockets from forming at the pickup, ensuring that the 255 LPH pump stays submerged even under extreme cornering forces. A continuous fuel head at the inlet translates into consistent volume delivery to the rail, which keeps electronic fuel injection pressure stable and engine response sharp. By mitigating fuel starvation events, the system protects injectors and the pump itself from rapid wear and erratic operation. Enthusiasts will notice smooth performance on both the street and the track.
Submerged Pump Module for Thermal Management and Longevity
Embedding the high-capacity Walbro 255 LPH pump directly inside the fuel tank immerses it in cool fuel, effectively reducing heat soak and extending service intervals. The close-coupled position shortens the pathway to the fuel rail, enabling faster pressure recovery when throttle demands spike. Integrating the module into the existing electrical circuit streamlines wiring and avoids unnecessary junctions that can compromise reliability. Rated to support up to 550 hp, this in-tank placement ensures sustained pressure and consistent flow rates under high-demand scenarios. Over time, cooler operating temperatures translate into a more durable pump and fewer maintenance callbacks.
Calibrated Sending Unit for Accurate Fuel Level Monitoring
The included fuel sending unit is engineered to mirror the original gauge resistance curves, allowing direct connection to factory instrumentation without adapters or rewiring. This calibration guarantees that the stock gauge needle reflects the true fuel volume, eliminating the guesswork often associated with custom installations. Maintaining an OEM feel in the cockpit, the system preserves original warning thresholds and float travel characteristics. Installers and drivers alike appreciate how this component blends effortless functionality with classic style. The result is a seamless upgrade that delivers precise feedback and peace of mind behind the wheel.
