1964 Pontiac GTO EFI Fuel Tank Kit 400 LPH Pump for LS and LT Swaps
When swapping in a modern LS or LT powerplant in your 1964 Pontiac GTO, inconsistent fuel delivery can dull throttle response under load, and the 1964 Pontiac GTO EFI Fuel Tank Kit - 400 LPH Pump eliminates that issue. Featuring a submerged Walbro 400 LPH pump that maintains steady flow during spirited acceleration or on the strip, it ensures pressure stays rock solid even with supercharged or high output setups. Installation uses original mounting points without altering the frame, so the kit bolts in and keeps the classic underbody intact. A calibrated sending unit matches the factory gauge curve for precise fuel level readings and the included vent filter and sealing gaskets protect injectors and lines from contaminants.
American Craftsmanship Ensuring Quality and Durability
Every component of the 1964 Pontiac GTO EFI Fuel Tank Kit is engineered and assembled in the USA, reflecting stringent quality control standards at every stage of production. From the precise machining of the fuel pump module to the seal integrity of the sending unit, domestic manufacturing ensures consistent tolerances that reduce variation between assemblies. Skilled technicians inspect each gasket, vent filter and mounting strap to guarantee leak-free operation over thousands of miles. This level of oversight translates into remarkable durability under the demanding conditions of spirited driving or strip duty. Owners benefit from the confidence that each kit embodies rigorous American workmanship, ready to support modern LS and LT engines without compromise.
Cohesive Module Design for Streamlined Maintenance
The integrated fuel pump module brings together the 400 LPH pump, sending unit, vent filter, and precision gaskets into a single, cohesive assembly ready for tank installation. By unifying these parts, the kit minimizes potential leak paths and simplifies removal for service or upgrade. Technicians can unbolt the module as one piece, reducing downtime on both street projects and race prep. The use of pre-assembled hardware and plug-in connectors further accelerates routine checks, filter replacement, or pump swaps. This design philosophy keeps maintenance straightforward while preserving system integrity.
Seamless Integration of Classic Underbody and Modern Fuel Management
Designed to utilize all original mounting points on the 1964 Pontiac GTO, Lemans, and Tempest chassis, this fuel tank kit preserves the vehicle's classic underbody appearance without modifications. The filler neck, straps and hardware match the factory geometry so that installation leaves the frame and suspension untouched. Underneath, the sending unit faithfully follows the stock gauge curve, delivering the familiar needle behavior drivers expect. This harmony between vintage style and modern EFI function allows enthusiasts to upgrade performance discreetly, maintaining show-quality aesthetics while benefiting from advanced fuel control.
Optimized Fuel Support for High Output LS and LT Powerplants
At the heart of this kit lies a Walbro 400 LPH pump engineered to satisfy the needs of boosted or 550+ horsepower LS and LT engine configurations. Its submerged mounting in the tank ensures continuous cooling, preventing heat-related performance drop-off during extended high RPM runs. The result is unwavering fuel pressure that keeps throttle response crisp under acceleration, whether launching off the line or powering through gears on the strip. Coupled with the calibrated sending unit and robust vent filter, the system delivers clean fuel at a consistent rate, safeguarding injectors and preventing vapor lock. This tailored support elevates engine reliability and efficiency across every driving scenario.
