340 LPH Fuel Pump and Fitting Kit for LS Engine Swaps
When dropping a modern LS powerplant into a 1991 through 2005 GM chassis installers often find stock tanks fall short of fuel flow and demand extensive plumbing work. This 340 LPH Fuel Pump and Fitting Kit features a genuine Walbro pump and anodized aluminum fittings that plug into factory hardlines or aftermarket rails without cutting or splicing and includes a low profile bracket to shorten the fuel feed path while retaining underbody clearance for exhaust and steering components. Its corrosion resistant finish stands up to ethanol blends and delivers steady performance under heavy throttle. Assembly includes plug in harness ends and secure hose terminations to reduce installation time on any LS engine swap.
Custom Frame Mount Design for 1967 to 1972 Chevy GMC Pickups
This gas tank kit features a purpose built frame mount that aligns precisely with the underside rails of 1967 to 1972 Chevy and GMC pickups. By matching the factory mounting points, it eliminates the need for custom brackets or extensive modifications, resulting in a clean installation that preserves original frame integrity. The mounting flange is engineered for consistent pitch and clearance, ensuring that exhaust and steering components remain unaffected. Installers benefit from a direct bolt-in solution that speeds up installation and restores a factory like appearance beneath the cab.
Engineered Fuel Delivery with Walbro 400 LPH Pump and Internal Baffles
At the core of this kit sits a genuine Walbro pump rated at four hundred liters per hour, capable of feeding engines up to seven hundred fifty horsepower with a stable stream of fuel. Surrounding the pickup, internal baffling channels fluid to maintain continuous supply during cornering, braking, or steep inclines. This design prevents fuel starvation and protects against pump cavitation, promoting consistent pressure at high engine speeds. The integrated reservoir holds eighteen gallons, giving tuners room to dial in fuel curves confidently under demanding throttle transitions.
Advanced Corrosion Protection with Galvanized Steel and Powder Coating
Constructed from heavy gauge steel treated with a zinc based galvanizing process, the tank resists rust and electrochemical attack from road salt and moisture. Over this base layer, a durable silver powder coat creates a seamless barrier that locks out contaminants and extends service life. The dual stage finish simplifies maintenance, allowing quick cleaning after off road excursions or long term storage. Together these treatments preserve structural strength and prevent leaks, guaranteeing the tank retains its full eighteen gallon capacity over many seasons.
Seamless Fuel Level Monitoring with Zero to Ninety Ohm Sending Unit and Side Fill Design
This kit includes a calibrated sending unit that operates on a zero to ninety ohm circuit, matching factory gauge clusters without any dash harness rewiring. Fuel level readings remain accurate throughout the entire capacity, giving drivers reliable feedback on remaining range. The side fill design positions the filler neck on the outer bed panel, avoiding interference with chassis rails and simplifying fuel nozzle access. Combined, these features deliver a cohesive appearance and functionality that integrate with stock interiors and instrumentation.
