1970 Chevy Monte Carlo A-Body LS EFI Fuel Tank Kit
Fitting an LS engine into a 1970 Chevy Monte Carlo A Body chassis demands precise underbody packaging and reliable fuel delivery, and the 1970 Monte Carlo EFI Fuel Tank Kit with its 255 LPH pump and notched shell addresses both needs. Its heavy gauge steel shell is precisely cut to clear modern exhaust routing and wider tires without any floorpan alteration. The 255 LPH fuel pump sits fully submerged to prevent cavitation and support engines up to 550 horsepower. Included sending unit, vent filter, filler neck, retaining straps, gaskets and hardware enable a straightforward installation that preserves chassis integrity and readies the system for electronic fuel injection conversion.
Notched Tank Design
The 1970 Monte Carlo EFI fuel tank kit features a precision notched tank design that delivers enhanced clearance for exhaust headers and rear tire movement. By recessing the inner panel at critical points, this kit ensures that large diameter headers and wide tires operate without interference under extreme suspension travel. This approach reduces the risk of heat transfer to the tank surface and prevents tire contact during high cornering loads. The result is a solution that maintains structural integrity while accommodating aggressive chassis setups.
Capacity and Fuel Delivery
Equipped with a 255 LPH Walbro pump, the system supports engines up to 550 horsepower without cavitation or flow drop at high RPM. The pump sits in a dedicated well that optimizes fuel pickup under acceleration, brake modulation and cornering. The integrated vent filter minimizes vapor accumulation for consistent pressure and safe operation. This balanced design allows modern injection systems to achieve precise spray patterns and accurate fueling across the entire rev range.
Installation and Engine Compatibility
This kit is engineered specifically for LS engine configurations and fits the 1970 Monte Carlo body shell without modification to the chassis rail. All mounting brackets align with factory holes and the kit uses sealed connectors for wiring the fuel pump and vent filter. Included hardware and detailed instructions enable a straightforward conversion from carbureted to electronic fuel injection setup, streamlining the transition to modern EFI control for reliable street or track performance.
