EFI-Ready Fuel Tank for 1970 Monte Carlo A-Body LS Swap

Achieve reliable fueling and effortless exhaust clearance in your 1970 Monte Carlo A-Body with this EFI-ready fuel tank, featuring a notched steel shell and a 255 LPH pump for up to 550 hp support. Integrated vent filtering cuts vapor buildup for enhanced safety while precision mounts preserve classic styling and ensure a seamless LS swap.

1970 Chevy Monte Carlo LS EFI Notched Fuel Tank Kit with 255 LPH Pump

Swapping an LS EFI system into a 1970 Chevy Monte Carlo A body can clash with modern exhaust routing and wider tire setups, and this EFI fuel tank kit resolves those fitment issues through its precise notched profile. By matching original mounting points it maintains ground clearance and preserves the car's classic rear floorpan geometry. The integrated 255 LPH Walbro pump supports engines up to 550 horsepower while a calibrated sending unit ensures accurate level readings during hard cornering. An inline vent filter captures vapors before they escape to reduce vapor buildup and maintain safer tank pressure under all driving conditions.

Precision Notched Profile for Classic Chassis Fit

The notched tank contour is engineered to follow the original 1970 Monte Carlo frame geometry, clearing modern exhaust routing and wider tires without trimming or modification. By matching factory mounting points, it preserves ground clearance and maintains the classic rear floorpan appearance. Installation requires no custom supports, reducing labor time and cutting out the guesswork for fabricators and home mechanics alike. The thoughtful design delivers a seamless integration that respects the A body's structural integrity.

High Capacity 255 LPH Pump Boosts Delivery for 550 HP Builds

This kit features a 255 liter per hour Walbro pump rated to support engines up to 550 horsepower, making it ideal for high output LS conversions. Its self priming action quickly fills supply lines at start-up, and the built-in check valve holds pressure when the engine is off, preventing fuel drain-back. Consistent fuel flow across all RPM ranges ensures sharp throttle response and reliable performance during spirited driving. Whether you're cruising or cornering hard, the system maintains steady pressure to keep the engine fueled precisely.

Calibrated EFI Sending Unit for Accurate Fuel Level Data

The included sending unit employs a low-friction float and a precise resistance curve that interfaces directly with modern engine control systems. It resists slosh and angle shifts during hard cornering, providing the ECU with stable, accurate tank level readings at all times. By delivering reliable data, it helps prevent lean or rich spikes and supports fine-tuned air-fuel ratios under varying load conditions. This level of precision protects engine components and contributes to optimal driveability.

Integrated Vent Filter Preserves System Safety and Emissions Control

An in-line vent filter captures fuel vapors before they escape, reducing vapor buildup that can lead to pressure spikes or vapor lock. It ties into the stock vent hose routing to maintain balanced tank pressure as temperatures and fuel levels change. By filtering out moisture and contaminants, the system prevents clogs in vent lines and extends the life of other fuel system components. This added safeguard gives drivers confidence during long highway runs or track sessions.

Built for precise installation and dependable performance. To complete your Larger capacity fuel pump Kit at 400 LPH, consider our 1970 Monte Carlo 400 LPH pump Tank Kit (notched).
