1971-1972 Chevy Monte Carlo LS EFI Fuel Tank Kit with 255 LPH Pump
When converting a 1971 to 1972 Monte Carlo to LS EFI power, maintaining chassis clearances while securing reliable fuel supply is essential, and this notched 255 LPH fuel tank kit meets both demands. Its precision shaped steel reservoir traces the contours of the Monte Carlo A Body frame rails to preserve clearance for exhaust paths and suspension linkages. Integrated top access to the 255 LPH pump allows removal and inspection without lowering the tank, cutting service time to minutes. The system sustains consistent rail pressure for engines up to 550 horsepower and arrives with all necessary mounting hardware for a straightforward installation.
Precision Shaped Reservoir for A Body Frame Rails
The steel tank shell is formed by laser cutting and press shaping to follow the contours of the 1971 to 1972 Monte Carlo A Body frame rails. This precise fit preserves clearance for the factory exhaust and rear suspension linkages to avoid heat soak or rubbing under load. By distributing fuel weight evenly under the chassis, this design supports stable handling and consistent ride height regardless of tank level. The steel resists deformation from road debris or impacts, ensuring the structure retains its exact shape over years of service. Dimensional accuracy also streamlines alignment of fuel lines and mounting straps, simplifying installation and test fitting.
Submerged Walbro 255 LPH Pump for Steady Fuel Delivery
Installed inside the tank, the Walbro 255 LPH pump delivers the consistent flow required to support up to 550 horsepower. Submerged operation keeps the pump motor cooled and lubricated by fuel, reducing wear and virtually eliminating the risk of vapor lock under high load or spirited cornering. Internal check valves maintain rail pressure after engine shutoff, preventing collapse and ensuring instant startup without priming. The pump's design also balances injector output, resulting in smooth throttle response during rapid throttle changes. Proven quiet operation makes it suitable for both daily driving and track duty.
Top Access Notch for Rapid Pump Service
A precisely cut notch in the tank's top surface provides direct access to the pump module without lowering the reservoir. Once the retaining ring is released, the module and strainer lift out in minutes, allowing quick inspection or replacement of components. This feature saves considerable workshop time, especially in a racing environment where fast turnarounds are critical. Early detection of debris buildup or strainer wear helps avoid unexpected fuel restrictions and engine lean conditions. Simplified service also reduces the chance of disturbing nearby fuel lines or suspension parts during maintenance.
Complete Kit Components for Effortless Installation
The kit arrives with all required parts, including the in tank pump module, sending unit, tank straps, filler neck, vent filter, gaskets, and hardware. Preassembled elements minimize guesswork in plumbing and wiring, aligning with stock gauge connectors and factory mounting points. The vent filter safeguards against pressure spikes during thermal cycles, while precision gaskets ensure a leak free seal at every joint. By consolidating all components into one package, technicians can streamline their workflow and complete the fuel system in a single session. This comprehensive approach reduces the need for supplemental parts and aftermarket adapters.
