1971-1972 Chevy Monte Carlo Notched EFI Fuel Tank Kit for LS Engine 400 LPH Pump
The 1971-1972 Monte Carlo EFI Fuel Tank Kit - 400 LPH Pump - Notched addresses the unique requirements of LS swaps in Chevy Monte Carlo models. A submerged 400 LPH Walbro pump cuts vapor lock risk and sustains flow under prolonged rpm, while an integrated sending unit delivers accurate level readings. The CNC machined notch precisely follows the frame rails and stock exhaust path to preserve suspension travel and prevent tire interference. Complete with tank straps, filler neck, vent filter, gaskets and mounting hardware, this complete assembly simplifies installation without extra fabrication.
Integrated Fuel Delivery System
The 1971-1972 Monte Carlo EFI Fuel Tank Kit is centered on a 400 LPH high-performance pump, calibrated to support supercharged or over 550 hp setups with steady pressure under extreme demand. By pairing the pump with an integrated fuel level sending unit, the system delivers precise flow alongside consistent tank-level monitoring. Drivers benefit from accurate gauge readings and reliable supply to the engine's feed rail, which is critical when tackling wide throttle openings or holding high boost. This cohesive approach reduces the risk of lean conditions during hard acceleration and helps maintain optimal combustion throughout every driving scenario.
Tailored Fit and Clearance Optimization
The notched tank design ensures proper exhaust and tire clearance in the Monte Carlo's original chassis environment. By carving strategic reliefs into the casting, this kit avoids interference with header collectors and modern wheel-and-tire packages, eliminating the need for system modifications or custom hangers. Furthermore, it is engineered to align with MuscleRods mounting points, ensuring accurate alignment of the fuel filler neck, straps, and pick-up assembly. This compatibility preserves factory ride height and drivetrain angles, preventing stress on fuel lines and prohibiting plumbing twists that could impair flow.
Durable Construction and Installation Convenience
Crafted from corrosion-resistant steel and finished with a durable coating, the fuel tank withstands harsh fuel additives and extended exposure to road contaminants. Each unit is supplied with pre-formed straps, gaskets, rubber isolators, and brackets, delivering everything required for a thorough install. The comprehensive hardware package reduces vehicle downtime, as technicians can fit the tank without sourcing additional parts. Clear instructions streamline inside-the-frame installation, allowing smooth integration into classic restoration projects while upholding modern performance demands.
