1970 Chevy Monte Carlo EFI Fuel Tank Kit with 400 LPH Pump for LS Swap
If you are tackling an LS swap in a 1970 Chevy Monte Carlo A Body chassis, this EFI Fuel Tank Kit addresses the crucial need for uninterrupted supply under rapid throttle changes and space for exhaust and rear tires. Its notched steel shell carves clearance around wheel arcs and piping while the integrated 400 LPH pump module sustains consistent pressure during sudden demand spikes. Beyond simple clearance, the built in baffling limits fuel slosh under lateral forces to maintain steady delivery during spirited driving. Installers will find bracket locations matching factory rails and all hardware included for a truly direct fit installation that resists corrosion and vibration over time.
Integrated 400 LPH Walbro Pump Ensures Steady Fuel Delivery
The in-tank 400 LPH Walbro pump module delivers consistent pressure under sudden throttle demands in LS-swapped Monte Carlo applications. Its internal design minimizes heat buildup and resists vapor lock when output requirements spike, preserving optimal injector timing and air to fuel ratios. By sustaining uninterrupted flow at peak demand, the pump supports configurations over 550 horsepower without causing lean conditions or surging. This reliability proves critical during spirited driving when rapid acceleration would otherwise starve a standard stock unit. Engineers and tuners alike will appreciate the precision fuel metering that underpins smooth throttle response and consistent performance at all RPM ranges.
Precision Notched Tank Design Provides Clearance and Fuel Stability
Each steel shell is CNC notched to clear exhaust tubing and rear tire arcs while maintaining maximum capacity for spirited driving. The tailored profile allows the tank to tuck close to the frame rails, preserving ride height and preventing unwanted contact. Internal baffling around the pickup reduces fuel slosh laterally, ensuring uninterrupted delivery under cornering forces and quick lane changes. This combination of clearance and stability means the assembly requires no extra trimming or fabrication to fit a 1970 A-Body chassis. Installers benefit from a component that merges precise chassis compatibility with critical dynamic performance.
Complete Direct Fit Kit Streamlines Monte Carlo Installation
This all-in-one EFI tank kit includes the pump module, sending unit, straps, filler neck, vent filter, gaskets and all mounting hardware needed for a bolt in assembly. Bracket locations match factory rail positions on the 1970 Chevy Monte Carlo A-Body frame, and the filler neck aligns with existing hoses and return lines for a plug-and-play hookup. With no drilling or welding required, the kit integrates seamlessly with stock fuel gauge and emission vents. The result is a streamlined retrofit that preserves chassis integrity, cuts install time and eliminates guesswork for technicians and home builders.
