Direct-Fit 255 LPH Fuel Tank for 1978-1988 G-Body LS

For a trouble free LS swap in your 1978 to 1988 G Body Monte Carlo, Malibu, or Grand Prix, the 255 LPH EFI Fuel Tank Kit integrates a robust Walbro pump and precision sending unit to guarantee smooth throttle response and exact fuel readings under demands up to 550 horsepower. Its direct install into factory mounting points requires no cutting or welding and saves hours on fabrication. Rugged steel construction and USA manufacture ensure dependable service across every mile.

1978-1988 LS Fuel Tank Kit for G-Body Monte Carlo Malibu Grand Prix

For LS swaps in 1978 to 1988 Monte Carlo, Malibu and Grand Prix G-Body models, this EFI fuel tank kit positions a 255 LPH Walbro assembly within the stock tank location to maintain steady flow under demanding load conditions. Its in tank pump placement combats heat build up and air ingestion during spirited acceleration while the integrated sending unit delivers accurate gauge readings through the factory cluster. Installation follows original mount points with supplied straps gaskets and filler neck to preserve underbody clearance and reduce labor time. USA made steel construction resists corrosion and engine vibration for consistent service on road or track.

Performance Driven Internal Pump Placement

The internal location of the 255 LPH Walbro pump keeps it fully submerged in fuel to shed heat rapidly and prevent fuel vapor formation under heavy load. This immersion ensures a stable pumping temperature and preserves consistent flow when the engine demands peak power. A fine mesh vent filter and precision flow passages reduce the risk of air pockets during acceleration and cornering. The result is a smooth throttle response and dependable operation across varied driving conditions.

Up to 550 hp Engine Support

At its core, this pump module is engineered to supply steady fuel volume for motors producing up to 550 hp, maintaining required pressure even at high rpm. The 255 liter per hour rating covers a broad power range without risk of starving the injectors during spirited driving. Its design accommodates elevated demands from turbo or naturally aspirated setups alike. By matching pump capacity to engine output, tuners avoid lean condition issues and safeguard performance.

Direct Fit Bolt in Installation and Durable Construction

This kit installs using the factory mounting points on Monte Carlo Malibu and Grand Prix frames without the need for alterations, preserving chassis geometry and underbody clearance. Included straps, gaskets, filler neck and hardware streamline the process and reduce shop time. The steel tank body and corrosion resistant fittings are fabricated in the USA under strict quality controls to resist vibration and surface damage. Seal materials endure repeated thermal cycles and fuel exposure for reliable service life.

Integrated Sending Unit for Reliable Fuel Level Monitoring

The built in sending unit employs a calibrated float and robust connectors to feed precise level data through the stock gauge cluster. This approach retains factory signal integrity and removes the need for aftermarket instruments. Connector housings resist corrosion from fuel vapors and guard against vibration effects for stable readings on road and track. Drivers benefit from confidence in remaining range without guesswork.

This MuscleRods solution delivers precise flow for more powerful engines. To step up to a larger capacity fuel pump Kit at 400 LPH see our 1978-1988 Monte Carlo 400 LPH pump Tank Kit.
