255 LPH Fuel Line and Regulator Kit for LS Engine Swaps
When tackling a street or track LS swap most builders want a fuel line that handles ethanol blends and keeps pressure rock steady. This Fuel Line and Regulator Kit - 255 LPH pairs a PTFE inner tube with a stainless steel braid to resist abrasion and chemical breakdown. It also features a preset 58 psi regulator and an OE style filter in a returnless layout to clear up engine bay real estate and simplify routing. Complete with AN fittings, clamps and mounting hardware the package arrives ready for a fast, leak free install.
Stainless Steel Braided PTFE Fuel Line for Ethanol Compatibility
The fuel line uses an inner tube of PTFE that is fully compatible with ethanol blends common in modern performance fuels. The woven stainless steel braid provides abrasion resistance and shields nearby wiring and painted surfaces from wear. This layered construction maintains integrity under vibration and prevents leaks even when tightly routed near sharp engine bay brackets. Made in the USA from corrosion resistant materials, the assembly delivers reliable service during street and track use.
Integrated Filter and 58 Psi Regulator Ensuring Stable Injector Feed
By combining an OE style fuel filter with a preset 58 psi regulator in one module, this kit guarantees injectors receive precise pressure the engine control unit expects. The fixed output removes the need to adjust valves, helping both newcomers and experts achieve consistent flow for clean tuning and strong throttle response. Integrating the filter and regulator also cuts potential leak points and streamlines the plumbing layout for a cleaner underhood package. This unified design reduces install time and supports reliable performance even under track demands.
Returnless System Design for Clean Routing and Reduced Heat Soak
The returnless layout eliminates a separate hose back to the tank, freeing up valuable engine bay real estate and simplifying line paths. Without a return leg, fuel remains cooler by staying out of looped circuits, which helps maintain consistent density during extended idling or hot ambient conditions. Included AN fittings, adapters, clamps, and hardware allow for a fast, tool friendly installation that minimizes guesswork and possible leak points. The result is a tidy engine bay and confident daily drive or street strip operation.
