1971-1972 Chevy Monte Carlo LS EFI Fuel Tank Kit with 255 LPH Pump
If you're swapping an LS engine into a 1971-1972 Chevy Monte Carlo A Body, this EFI fuel tank and 255 LPH pump assembly ensures factory alignment with original frame bracket locations and vent fittings to prevent clearance conflicts. By housing a Walbro 255 LPH pump inside a steel cell, the design keeps pump temperature lower and quiets vibrations while supporting up to 550 hp in both naturally aspirated and forced induction setups. With all necessary straps, gaskets and filler neck hardware included, installers can achieve consistent fuel delivery while preserving factory routing and avoiding clearance issues under the chassis.
Precise Frame Alignment for LS Swaps
With carefully matched bracket and vent fitting points the tank sits exactly where the original unit did on a 1971 to 1972 A Body chassis. This precise fit avoids the need for weld work or bracket moves and preserves the integrity of the frame structure. By eliminating clearance conflicts installers save hours that would otherwise be lost in trial fitting and can focus on fuel line routing instead. The result is a secure foundation that stands up to vibration without seal fatigue or misalignment issues.
Steel Cell Housing for Thermal Control and Quiet Operation
The heavy steel cell design encases the pump and ensures it runs in a bath of cool fuel that absorbs heat under full load. By maintaining lower operating temperatures the pump avoids early wear and supports higher output demands in both naturally aspirated and forced induction LS engines. The steel walls also help dampen noise and reduce vibration transmitted to the chassis which leads to a quieter cabin. This combination of heat management and acoustic control preserves pump life and enhances driver comfort on long hauls or track days.
In-Tank Pump Positioning Enhancing Fuel Delivery
The in-tank placement positions the 255 liter per hour pump right in the fuel stream for immediate flow and consistent pressure during rapid throttle changes. Drawing fuel directly from the cell prevents vapor lock and lean condition risks under heavy load so engine response remains crisp at wide open throttle. This location also uses the fuel as a sound and vibration damper, smoothing out pressure spikes and extending service life. The design supports outputs up to 550 horsepower in midrange V8 layouts without compromise.
Complete Module Integration Simplifies Installation
Every necessary component from sending unit to vent filter comes in one package so plumbing and electrical work can begin right away. Prefit gaskets ensure leak free joints while steel straps and a factory style filler neck snap into place without puzzling over missing adapters. The included hardware kit covers bracket bolts and vent hoses for a single purchase solution that cuts install time drastically. This full scope approach takes guesswork out of LS fuel system upgrades and prioritizes reliable performance under all driving conditions.
