1968-1969 Cutlass/Skylark EFI Fuel Tank Kit for LS Swaps
If you are fitting an LS powerplant into a classic A Body chassis the 1968-1969 Cutlass / Skylark EFI Fuel Tank Kit ensures reliable flow under hard acceleration. By placing a 255 LPH Walbro pump along with the sending unit seals and mounting hardware into the original tank opening it matches factory fit and keeps pressure steady whether cruising or accelerating out of turns. Proper alignment of the outlet with the LS fuel lines reduces heat soak that can lead to vapor lock during spirited driving and supports consistent performance on street or strip.
Precision Machined Module for Seamless Tank Integration
The custom module combines the fuel pump, sending unit, seals and vent filter into a single assembly that drops into the original tank opening of 1968 and 1969 Cutlass and Skylark A Body cars. Precision machining ensures each gasket seats correctly against factory grade tolerances, preventing leaks and preserving accurate level readings on vintage gauges. By maintaining the pump outlet at the ideal height within the fuel, the assembly remains fully submerged under normal driving angles, avoiding cavitation and noise during cornering. This integrated design eliminates the need for aftermarket brackets or adapters and keeps the undercarriage free of extra fittings for a clean appearance.
Robust 255 LPH Walbro Pump Ensuring Steady Flow
At the core of the kit is a 255 LPH Walbro unit rated to supply enough fuel for engine calibrations up to 550 horsepower. Its durable internal housing resists wear from sustained operation and preserves performance under rapid throttle changes. The streamlined flow path inside the pump reduces turbulence and heat generation, which can degrade fuel quality and alter injector timing. Consistent delivery of high volume fuel prevents pressure drop during sharp accelerations or steep inclines, giving tuners a reliable base to refine engine mapping. As a result, drivers experience stable pressure whether cruising on the highway or pushing hard on track.
Comprehensive Kit Simplifies LS EFI Conversion
This in tank kit arrives complete with the pump module, sending unit, tank straps, filler neck adapter, vent filter, precision gaskets and all necessary hardware. A detailed instruction guide leads technicians and home builders through each installation step, from strap placement to hose routing, reducing the chance of missing fittings and eliminating trips to the parts counter. The tank straps and mounting bolts are engineered for secure engagement and resistance to vibration over time. By including every component required for a direct replacement in one package, this kit shortens labor hours, ensures correct clearances and delivers a solid foundation for reliable EFI fuel delivery.
Optimized Fuel Line Routing to Minimize Heat Buildup
The pump module's outlet is oriented to match LS EFI line positions, allowing shorter hose runs that stay clear of hot exhaust manifolds and engine block surfaces. Reducing the length of exposed fuel lines helps preserve fuel density and prevents vapor lock in high temperature environments. The vent filter is positioned to follow factory routing, maintaining proper tank pressure under rapid throttle transitions and preserving original flow characteristics. By avoiding sharp bends and kinks, hose wear is minimized and flow restriction is prevented, ensuring consistent fuel delivery whether navigating city streets or running laps on the track.
