Fuel Line and Regulator Kit for LS Engine Swaps
For LS engine swap projects that demand a steady feed and compatibility with ethanol blends, the Fuel Line and Regulator Kit - 255 LPH brings together chemical resistant materials and precise pressure control. It uses a PTFE inner tube wrapped in a stainless steel braid to withstand abrasion and protect nearby wiring or painted surfaces during spirited driving. A factory preset 58 psi regulator mates to an OE style filter in a returnless layout to reclaim engine bay space and simplify hose paths. Included AN fittings, clamps and mounting hardware support a tool friendly install that helps eliminate leak points.
Chemical Resistance and Structural Integrity of PTFE Stainless Steel Braided Line
The fuel line's inner P.T.F.E. tube offers exceptional compatibility with ethanol blends common in modern high-octane fuels. Wrapped in a woven stainless steel braid, the assembly resists abrasion and shields adjacent wiring or painted surfaces from wear during spirited driving. This layered structure also maintains its shape under engine vibration, preventing kinks and ensuring lasting leak-free operation. Built with corrosion-resistant materials in the USA, it delivers durable performance in street and track environments.
Integrated Filter and 58 psi Regulator for Consistent Fuel Delivery
By combining an OE style filter with a preset 58 psi regulator in one compact module, this kit delivers stable pressure directly to LS injectors without additional adjustment. The fixed output setting aligns with factory ECU expectations, simplifying tuning and preserving throttle response under load. Consolidating the filter and regulator into a single unit reduces potential leak points and streamlines underhood plumbing. As a result, builders benefit from cleaner fuel delivery and lower installation complexity.
Returnless Architecture Minimizing Heat Soak and Space Consumption
This returnless layout eliminates the traditional hose routed back to the tank, freeing engine bay real estate and shortening hose runs. With no return leg circulating warm fuel near hot components, the system helps maintain consistent density during extended idling or high-temperature operation. Shorter runs mean less chance of pressure drop and simpler routing around engine accessories. The tidy arrangement contributes to a well-organized bay and more predictable fuel temperatures under varied driving conditions.
Comprehensive Component Kit for Quick Leak Free Installation
Every element needed for a tool-friendly install arrives in the kit, from the threaded PTFE stainless steel braided line to the OE style filter/regulator combo. Precision-machined screw-together fittings fit LS fuel rails and regulator outlets without adapters, while additional AN style connectors cover the path from tank to rail. Line clamps and mounting hardware simplify securing the assembly to the chassis, eliminating guesswork and reducing the chance of leaks. This all-in-one package ensures consistent build quality and faster project completion.
