Direct-Fit LS Fuel Pump and Fitting Kit for 3rd Gen F-Body
When tackling an LS swap in a third generation Camaro fuel delivery is critical and this Fuel Pump and Fitting Kit for 3rd Gen F-Body installs in the factory tank to keep pressure steady under hard acceleration. Its machined fittings align with factory EFI sender ports for factory tank integration eliminating custom adapters or line cutting. Crafted from US made alloys treated to resist ethanol blends and road salts this assembly delivers reliable service from daily drives to track sessions. Built around a Walbro 255 LPH pump this tank design preserves the original underbody profile and supports future fuel system expansion without extra adapters.
Sustained Fuel Pressure for LS Swaps
The core of this kit is the Walbro 255 LPH in tank pump, selected to maintain a stable view of fuel pressure under full throttle across demanding driving conditions. By operating entirely inside the factory tank, the pump avoids exposure to heat soak and noise while preserving the original underbody appearance. Its proven flow capacity keeps the LS engine within the optimal air fuel window during hard acceleration, reducing the risk of lean spots that can lead to detonation and component stress. Every unit has been validated on both street and track to ensure the fuel system remains the cornerstone of swap reliability.
Streamlined Installation with Factory Tank Integration
Vehicle specific fittings eliminate any need for cutting lines or jury rig adapters by matching the exact dimensions of third generation Camaro and Firebird EFI sender ports. Each adapter is precision machined and paired with premium O rings to create a leak proof seal that resists compression set and chemical attack from modern ethanol blends. Technicians and home builders alike benefit from a drop in assembly that aligns with factory bolt patterns and retains the original tank structure. This seamless fit keeps installation time to a minimum and preserves tank integrity without alteration.
Alloy Construction Optimized for Corrosion Resistance
All metal components are crafted in the United States from selected steel alloys treated with a corrosion inhibiting finish designed to withstand ethanol enriched fuels and road salt exposure. This protective layer prevents surface pitting and slows the onset of material fatigue, extending service intervals and reducing maintenance costs. By guarding against moisture ingress and chemical attack, the assembly keeps fuel system contaminants at bay and ensures consistent performance in varied climates. Whether navigating winter slush or summer rain, this design delivers lasting operation.
Expandable Platform for Future Fuel System Upgrades
This fitting kit is more than a single pump solution; it establishes a modular foundation for progressive fuel system enhancements. Included adapters interface directly with the 255 LPH fuel line and regulator kit, enabling straightforward installation of pressure control or additional filtration without sourcing new hardware. If power goals rise, the same drop in assembly will accommodate higher capacity pumps and adjustable regulators while retaining proper alignment and leak free sealing. The result is a flexible platform that evolves with your performance needs.
