1970 Chevy Monte Carlo A-Body EFI Fuel Tank for LS Swap with 400 LPH Pump
When fitting an LS mill into a 1970 Chevy Monte Carlo A-Body, sudden throttle surges demand a fuel tank that maintains a steady supply. The 1970 Monte Carlo EFI Fuel Tank Kit with 400 LPH Pump Notched combines a reliable Walbro 400 LPH unit and a notched tank design that clears exhaust piping and rear wheels while keeping fuel close to the pickup. Since the shell mates directly with factory frame rail mounting points, no cutting or custom brackets are required for installation. Premium materials resist corrosion and hold steady pressure under spirited driving.
Walbro 400 LPH Pump Maintains Consistent Fuel Pressure
The genuine Walbro 400 LPH pump is engineered to deliver steady flow even during sudden throttle demands. By limiting internal heat buildup, it extends service life under repeated high load and supports precise injector timing. Drivers of supercharged or over 550 horsepower vehicles will notice sharper throttle response and reduced risk of fuel starvation on hard acceleration. This level of reliability is essential for both spirited street use and track sessions.
Notched Tank Profile for Clearance and Fluid Control
CNC machined notches in the tank shell clear exhaust routing and rear wheel arcs without altering chassis rails. This profile keeps fuel close to the pickup, minimizing slosh during cornering or aggressive launches. The cutouts follow the frame rail contours, enabling installation without cutting or custom brackets. The design strikes a balance between space efficiency and fluid stability to ensure uninterrupted supply to the pump.
True Direct Fit Installation for 1970 Monte Carlo A Body
All mounting points, strap locations, and filler neck orientation match the factory frame rails of the 1970 Monte Carlo A Body. Installers can bolt the tank in place without fabrication, then connect hoses and wiring straight away. The complete kit includes the in-tank pump module, sending unit, tank straps, filler neck, vent filter, gaskets, and hardware. This comprehensive approach saves shop time and delivers a secure, leak-free assembly.
