Consistent 255 LPH Walbro Pump Performance
The heart of this fuel tank kit is the in-tank 255 LPH Walbro pump, calibrated to maintain a steady supply of fuel for LS engines up to 550 hp. By operating within precise flow tolerances, the unit prevents fuel starvation during rapid acceleration or sustained high-RPM use. Its integrated module design houses the pump and sending components in one assembly, reducing internal turbulence and pressure fluctuations. This consistency is vital for tuning accuracy and throttle response, especially on vehicles transitioning between street cruising and spirited track runs.
Tailored Direct Fit for G-Body Chassis
Every component in this kit is engineered specifically for 1981-1988 Oldsmobile Cutlass G-Body frames, eliminating the need for custom brackets or fuel line rerouting. The filler neck and vent filter snap into place with factory mounting points, while the sending unit aligns perfectly with the existing tank opening. This seamless integration reduces installation time and minimizes the risk of leaks or misalignment. Technicians and enthusiasts alike benefit from a straightforward bolt-in process that delivers professional results without machining or fabrication.
Engineered for Reliability in Street and Track
Constructed from premium-grade materials, the tank, straps, and hardware in this kit are built to resist corrosion and mechanical fatigue under diverse driving conditions. The gaskets and seals provide secure, leak-free joints, maintaining system integrity even under thermal cycling and vibration. Whether subjected to daily commuting or high-load track sessions, the assembly retains its form and function. This durability ensures your LS swap maintains consistent fuel delivery and delivers dependable performance mile after mile.
