1970 Monte Carlo EFI Fuel Tank Kit - 400 LPH Pump

1970 Chevy Monte Carlo EFI Fuel Tank Kit with 400 LPH Pump for LS Swap

For enthusiasts fitting an LS engine into a 1970 Chevy Monte Carlo A-Body, the 1970 Monte Carlo EFI Fuel Tank Kit - 400 LPH Pump is engineered to deliver steady fuel flow and simplify installation during your engine swap. This kit integrates a 400 LPH Walbro pump and sending unit directly into the tank to eliminate extra plumbing and support applications above 550 hp or forced induction. Durable construction, built-in vent filtration, and complete hardware with tank straps ensure corrosion resistance and smooth mounting to factory fittings.

Precision Fuel Supply for Supercharged LS Engines

The 400 LPH Walbro pump included in this kit ensures a steady stream of fuel under the most demanding conditions, supporting supercharged setups or engines that exceed 550 hp. By maintaining consistent pressure, the system prevents lean spots and preserves optimal combustion across the rpm range. This reliable flow rate is critical for maximizing output and protecting internal components from fuel starvation during rapid acceleration.

Integrated In Tank Pump Module for Simplified Installation

Housing the fuel pump and sending unit directly inside the tank eliminates the need for external mounting brackets and convoluted plumbing. Installers simply secure the module with the provided gaskets and hardware, cutting down labor time and reducing potential leak points. This streamlined approach is particularly advantageous when adapting an LS engine to the confined spaces of a 1970 Chevy Monte Carlo A Body chassis.

Corrosion Resistant Tank Design with Built In Vent Filtration

The tank is constructed from materials chosen to withstand harsh driving cycles and resist corrosion over time. An integrated vent filter keeps debris and moisture out of the fuel system, safeguarding the pump and injectors. Complete with sturdy straps and mounting hardware, the assembly secures firmly to factory points without the need for custom brackets.

Complete Assembly with All Necessary Components

This all-in-one kit delivers the in-tank pump module, sending unit, filler neck, gaskets, tank straps, vent filter, and mounting hardware in a single package. By providing every part required for an LS swap, it eliminates sourcing delays and ensures compatibility with EFI systems. Whether you're a seasoned technician or a dedicated hobbyist, having the full assembly at your fingertips streamlines the conversion process and guarantees a precise fit.
