LS EFI Fuel Tank Kit with 400 LPH Pump for 1970 Chevy Monte Carlo
If you are fitting an LS powerplant into a 1970 Chevy Monte Carlo A Body this EFI tank kit addresses clearance and fuel starvation in one package. Its precisely notched shell provides ample room for rear wheel arcs and exhaust runs while keeping fuel close to the pickup under hard cornering. The kit includes a 400 LPH pump module engineered for steady delivery during sudden throttle surges. Mounting brackets align with factory rails so no cutting or fabrication is required and standard hardware completes the installation quickly.
Consistent Fuel Delivery Under Intense Throttle Demand
The 400 LPH Walbro pump module inside the tank is engineered to sustain precise fuel pressure even under sudden throttle surges, ensuring continuous delivery for LS swapped V8 powerplants. With its robust internal architecture, the assembly limits heat build up and avoids vapor lock during extended high load operation. Maintaining consistent flow at peak demand supports precise injector timing and optimal air fuel ratios, translating to sharper throttle response and smoother power delivery. This stability is particularly beneficial in forced induction or high output setups exceeding 550 HP, where interruptions in supply can risk detonation. Drivers will notice predictable performance in both spirited street driving and demanding track sessions. The pump's proven design also reduces the likelihood of premature wear, offering reliable service through many operating cycles.
CNC Machined Notches for Exhaust and Wheel Clearance
Each fuel tank shell is precisely CNC machined to incorporate clearance notches that accommodate rear tire arcs and tight exhaust routing without compromising structural integrity. By allowing the shell to nestle close to the frame rails and exhaust components, the design prevents contact damage and preserves critical ground and suspension clearances. At the same time, the notches keep fuel adjacent to the pickup during aggressive cornering, effectively minimizing slosh and avoiding intermittent starvation. This results in a reliable supply under lateral G forces and hard launches. The manufacturing process also ensures repeatable tolerances so every unit fits the Monte Carlo A body configuration exactly. Installers benefit from the accuracy of a factory style part, eliminating the need for cutting or custom bracket fabrication.
Seamless Fitment with Factory Frame Rails
Mounting brackets and strap bosses on this kit align exactly with the original frame rail locations of the 1970 Monte Carlo A body, transforming what might be a complex retrofit into a straightforward bolt in project. The filler neck orientation matches the stock geometry, allowing existing fuel hoses and return lines to connect without modification. A vent filter and sending unit are pre positioned for direct compatibility with the factory dash gauge and emission plumbing. The kit supplies all necessary hardware, tank straps, gaskets and fasteners, removing guesswork often encountered when adapting modern components to a classic chassis. This careful attention to fitment reduces shop labor hours and the need for cutting tasks. As a result, installers can complete the conversion faster and with confidence in alignment and system integrity.
Corrosion Resistant Construction for Lasting Reliability
Crafted from corrosion resistant steel and featuring precision MIG and TIG welds at critical seams, the tank shell is built to resist the rigors of spirited driving and prolonged service. The material choice delivers an optimal balance of strength and fatigue resistance so the shell endures road vibration and pressure fluctuations without deformation. Weld locations are reinforced to maintain consistent internal pressure, preserving fuel containment and preventing leaks even under repeated expansion and contraction cycles. A robust protective coating guards the interior and exterior surfaces from rust and chemical attack, extending service life in corrosive environments. This durable construction minimizes maintenance intervals and lowers the total cost of ownership for high performance builds. Owners can trust the system to maintain reliable operation through many seasons of use.
