1971-1972 Chevy Monte Carlo LS EFI Fuel Tank Kit with 400 LPH Pump
Whether you are working on a street cruiser or a track ready LS conversion the 1971-1972 Monte Carlo EFI Fuel Tank Kit - 400 LPH Pump solves the fuel starvation and vapor lock challenges in A Body chassis. This custom reservoir fits between stock frame rails without trimming and houses a submerged 400 LPH Walbro pump that stays cool under the fuel surface for consistent flow during heavy acceleration or hard cornering. A built in vent filter maintains stable pressure while a precision level sender delivers accurate gauge readings no matter the fuel level. Complete hardware and instructions guide a straightforward installation for any skill level.
Optimized Placement of the 400 LPH Walbro Pump
Positioning the 400 LPH Walbro pump fully submerged in the tank offers critical advantages for LS conversions in a 1971 to 1972 Monte Carlo. Immersion beneath the fuel surface prevents vapor formation around the unit, eliminating the risk of engine hesitation under heavy acceleration or sustained load. Continuous exposure to coolant fuel maintains a stable operating temperature, which in turn extends pump life and safeguards against failure in spirited driving. Mounting the pump internally also cushions it from road vibration, reducing noise and mechanical stress. This arrangement streamlines fuel line routing by minimizing bends, helping to preserve maximum flow capacity for engines pushing beyond 550 hp.
Integrated Vent Filter and Fuel Level Sender Coordination
By combining a vent filter with a precision fuel level sender, the kit sustains consistent internal pressure and reliable gauge feedback under all driving conditions. The vent filter blocks airborne contaminants from entering the tank when pressure equalization is needed, preventing air locks that could starve the pump. At the same time, the calibrated sending unit directly senses fuel height, delivering accurate readings even when cornering forces shift the fuel away from the pickup. This cooperation stops false low fuel warnings and guards against dry pump operation, ensuring the system remains efficient and dependable on winding back roads or during track sessions.
Custom Fit Tank Design for 1971 to 1972 Monte Carlo
This fuel tank is sculpted to snugly nest between the factory frame rails of the Monte Carlo A Body chassis without trimming or fabrication. Its precise contours align with original mounting points, preserving the vehicle's underbody profile and structural integrity. Included straps, gaskets, and filler neck components match factory specifications, allowing the reservoir to integrate seamlessly into the existing chassis architecture. Detailed instructions guide installers through the removal of the stock tank and the secure attachment of the new unit, reducing labor time and eliminating guesswork for technicians of all experience levels.
Complete Installation Kit for Seamless Assembly
The all-included kit arrives ready for assembly, featuring a preassembled pump module and clearly labeled hardware packs for quick identification. Along with the tank, installers receive the sending unit, tank straps, vent filter, filler neck, sealing gaskets, and mounting bolts. A step by step instruction manual details each phase of the process, ensuring correct sequence and torque values for a leak free setup. By supplying every component in one package, the kit streamlines the swap, removes the need to source additional parts, and cuts downtime for both street and performance builds.
