EFI Fuel Tank Kit 400 LPH Pump for LS and LT Swaps 1968-1970 Pontiac GTO/Lemans
Swapping an LS or LT powerplant into a 1968-1970 GTO or Lemans raises questions about delivering consistent fuel at high demand. This EFI Fuel Tank Kit with its 400 LPH pump replaces the stock unit and fits directly into the original A-Body tank. Installation proceeds without welding or special tools thanks to the complete tank module and precision sending unit. Engineers optimized the module for LS and LT conversions to support powerplants up to 550 hp with reliable fuel level monitoring.
Robust 400 LPH Fuel Delivery Capability
The EFI Fuel Tank Kit features a 400 LPH Walbro pump engineered to supply consistent flow for LS and LT engine conversions up to 550 HP, including supercharged applications. The pump maintains stable pressure under high engine demands, preventing lean spots during acceleration. Positioning the pump inside the tank reduces heat soak and vapor lock, ensuring reliable operation during extended performance runs. By matching flow capacity to modern fuel injection systems, it preserves engine response from startup to full throttle.
Installation Without Welding for Classic A-Body Models
This kit includes a complete tank mounted module designed to install directly into 1968 to 1970 Pontiac GTO and Lemans tanks without cutting or welding. All necessary straps, filler neck, vent filter, gaskets, and hardware are included for a straightforward swap. The design allows DIY enthusiasts to upgrade fuel delivery in a single afternoon using basic hand tools. Clear alignment of mounting points and preinstalled components minimize preparation time, reducing shop hours.
Integrated Precision Sending Unit for Accurate Fuel Reads
Maintaining awareness of fuel levels is critical when operating high output engines and this kit's sending unit offers finely tuned calibration. It provides smooth, linear resistance changes across the full tank range to eliminate erratic gauge behavior. Durable construction resists vibration and corrosion commonly found in fuel environments. This level of accuracy gives drivers confidence in their range calculations, reducing unexpected refuels during spirited driving.
