LS EFI Fuel Tank Kit for 1968-1970 Pontiac GTO
When fitting an LS engine into a 1968 to 1970 Pontiac GTO A Body, the GTO / Lemans EFI Fuel Tank Kit with 255 LPH Walbro pump addresses flow limitations by combining a steel reservoir capable of handling up to 550 hp. The in tank module uses multi angle pickup tubes to prevent fuel starvation during hard cornering or rapid throttle events. Designed to bolt to factory mounting points, it preserves suspension geometry and aligns with stock fuel lines for direct connection to LS engine harnesses. The kit arrives complete with a sending unit, filler neck, vent filter, tank straps, gaskets and hardware, ensuring a precise fit and reliable performance in LS conversions.
Precision Fit for 1968–1970 Pontiac GTO and Lemans
This fuel tank kit is engineered to match the original chassis contours of 1968 through 1970 Pontiac GTO and Lemans models. With its direct fit approach, the tank drops into the original mounting points without requiring crossmember trimming or custom brackets. High grade steel construction ensures that the original rear frame rails remain unaltered, preserving factory clearances around suspension components and exhaust paths. Installers benefit from a seamless retrofit that maintains the car's heritage appearance while upgrading to modern fuel system standards.
High Flow Fuel Delivery for Up to 550 Horsepower
Equipped with a 255 LPH in-tank pump from Walbro, this kit delivers ample fuel volume and consistent pressure for LS engines making up to 550 horsepower. The pump housing and outlet have been optimized to reduce turbulence and heat soak, so fuel temperature remains controlled under extended high-load driving. By matching pump performance to engine output, the system prevents lean condition risks during wide-open throttle runs and provides the safety margin needed for spirited street or track use.
Seamless LS Engine Integration with MuscleRods Compatibility
Designed for LS powerplants, this kit aligns perfectly with a variety of cylinder head choices and intake manifolds. When paired with MuscleRods mounts, it guarantees correct engine placement and proper drivetrain angles. This engineered partnership minimizes vibration and driveline stress, promoting longer component life and smoother power delivery. The result is a dedicated installation that respects chassis geometry and delivers optimal transmission input shaft alignment.
Durable Construction and Simplified Installation
Built from corrosion-resistant steel and finished with a factory-style coating, the tank resists rust from road salts and fuel additives. All mounting hardware, rubber isolators and wiring connectors are included for a plug-in installation that adheres to OE wiring standards. Internal baffling controls fuel slosh during acceleration and cornering, while service-friendly access ports allow filter or pump replacement without tank removal. The comprehensive kit streamlines installation, cutting shop time and delivering lasting reliability.
