255 LPH LS Fuel Tank Kit for 1970 Monte Carlo A-Body

Achieve uninterrupted fuel delivery up to 550 hp in your 1970 Monte Carlo A-Body thanks to the precision-engineered 255 LPH pump and tailored tank design. Durable construction ensures perfect fit with no modifications, boosts economy through EFI optimization and resists starvation under spirited or daily use.

1970 Chevy Monte Carlo LS Fuel Tank Kit with 255 LPH Pump

Anyone swapping an LS engine into a 1970 Chevy Monte Carlo knows that fuel delivery can make or break a build and this 1970 Monte Carlo EFI Fuel Tank Kit with 255 LPH Walbro pump maintains steady pressure for setups up to 550 horsepower. Designed to drop straight into the A Body chassis with factory mount alignment, the assembly arrives complete with tank straps, gaskets, vent filter and mounting hardware. Its in tank pump configuration promotes cooler fuel temperatures and reduces noise while preventing starvation during heavy acceleration or extended highway runs. With every component tailored for direct fit, installation takes minutes and preserves the original undercarriage layout.

Precision A Body Fitment for 1970 Monte Carlo

This fuel tank kit is engineered specifically for the A Body chassis of the 1970 Monte Carlo, aligning perfectly with existing frame rails and factory mounting points. By matching the original undercarriage geometry, it eliminates trimming or adapter brackets and maintains the car's classic stance. The integrated filler neck and vent filter assembly ensure proper clearance and ventilation without interfering with suspension or brake components. Installation is streamlined, allowing technicians or home builders to secure the tank in minutes and preserve the vehicle's structural integrity.

Submerged Pump Design for Consistent Fuel Delivery

At the core of this assembly sits a 255 LPH Walbro pump fully submerged in the tank, which keeps fuel temperatures lower and reduces operational noise compared to external setups. The in-tank module benefits from a built-in bypass valve that prevents over-pressurization and maintains steady flow even under heavy acceleration or sustained highway cruising. This design supports up to 550 horsepower and delivers rock-solid throttle response, so the LS engine never encounters starvation or lean-condition spikes. Cooler fuel also helps protect internal pump components and extends service life.

Comprehensive Kit Layout for Effortless LS Engine Swap

Rather than sourcing parts from multiple vendors, this package arrives complete with every component needed for an LS engine conversion in a Monte Carlo. Included are the pump module, calibrated sending unit, tank straps, filler neck, vent filter, gaskets and mounting hardware. Each piece is selected for direct compatibility, removing the guesswork and effort often spent gathering fittings and adapters. This all-in-one approach speeds up the swap process and ensures all connections meet EFI standards from day one.

EFI Operation Enhancing Efficiency and Engine Protection

Modern electronic fuel injection technology adapts metering to engine load and temperature, improving fuel economy on routine drives while safeguarding against vapor lock on hot days. By maintaining stable pressure through wide-open throttle, the system prevents lean-condition surges that can damage pistons, rods or valves. Drivers benefit from smoother power delivery and lower consumption, and the engine enjoys consistent lubrication from the fuel rail under every driving scenario. This balance of efficiency and protection keeps an LS swap running strong for years of spirited use.
