LS EFI Fuel Tank Kit for 1978-1988 G-Body Monte Carlo Malibu Grand Prix
When converting your 1978-1988 G-Body to LS power, fuel supply becomes a critical concern and this EFI Fuel Tank Kit makes that transition straightforward. Featuring an in-tank module with a 255 LPH pump, the setup sustains consistent pressure for engines up to 550 horsepower without stretching factory lines. Installation bolts directly into the stock tank location without trimming or fabrication, preserving the original chassis geometry and simplifying fitment. With accurate level sensing and an optimized flow path, you get reliable fueling under varied driving conditions for any classic Monte Carlo, Malibu or Grand Prix swap.
Precision Fitment for G-Body Installation
The EFI fuel tank kit bolts directly into the original tank location on all 1978-1988 G-Body models, eliminating trimming or fabrication. This precise fitment preserves the factory chassis geometry and aligns perfectly with existing fuel lines and mounting points. Installers benefit from a streamlined process that requires only the supplied straps, filler neck, gaskets, and hardware. The result is a clean, factory-style appearance with no compromise to structural integrity or clearance.
Consistent Fuel Delivery with 255 LPH Walbro Module
At its heart, the kit features a 255 LPH Walbro pump capable of supporting engines up to 550 horsepower while maintaining stable fuel pressure under hard acceleration. The in-tank design reduces fuel aeration and heat soak, ensuring a steady flow even in spirited driving or track conditions. By optimizing the flow path within the tank, this module delivers fuel on demand and improves throttle response across the rpm range. Drivers experience smoother acceleration and reduced risk of fuel starvation during cornering or incline runs.
Integrated Sending Unit for Reliable Level Monitoring
An integrated sending unit provides precise fuel level readings that outclass aging stock sensors. The calibrated float arm and sealed electrical connections resist vibration and corrosion, delivering accurate range information at all fill levels. This enhancement removes guesswork on extended drives and supports confident fuel management without aftermarket gauges. Owners gain consistent feedback on tank capacity, preventing unexpected fuel runs when pushing the limits of their LS-powered swap.
American Made Construction for Lasting Durability
Proudly manufactured in the USA, each component undergoes rigorous quality control to ensure long lasting service life. The tank straps and vent filter are fabricated from corrosion-resistant materials, while the filler neck and module housing use robust alloys designed for fuel compatibility. All gaskets and hardware are selected to maintain seal integrity under thermal cycling and vibration. This attention to detail delivers a fuel system that stands up to daily driving, weekend cruises, and competitive events without compromise.
