Return Style Fuel Line and Filter Kit for LS Swaps
When outfitting your project with an LS engine you need a fuel line kit that maintains consistent pressure and guards against vapor lock and the Return Style Fuel Line and Filter Kit delivers on both counts. Crafted from PTFE stainless steel braided lines wrapped in a black protective jacket it maintains 58 psi while sending surplus fuel back to the tank. Complete fittings and clamps support straightforward installation on early LS rails and the included billet aluminum filter traps debris before it reaches the injectors.
Durable PTFE Stainless Steel Braided Fuel Lines
The fuel lines are constructed from PTFE stainless steel braid wrapped in a tough black jacket, providing exceptional resistance to abrasion and protection for adjacent wiring or paint. This design stands up to today's ethanol blends and harsh roadside conditions without swelling or degrading. Made in the USA with corrosion-resistant materials, these lines deliver consistent performance and a clean appearance under the hood, giving builders confidence in their fuel delivery setup.
Return Style Layout for Stable Pressure Control
This kit's return style configuration works seamlessly with early LS fuel rails and on-rail regulators, ensuring stable fuel supply by routing excess volume back to the tank. By maintaining 58 psi at the rail, it minimizes the risk of vapor lock during hard driving or hot ambient temperatures. The direct-fit layout simplifies hose routing and balances pressure, so the engine receives the precise fuel flow required for reliable operation.
Billet Aluminum Filter for Engine Debris Protection
The included billet aluminum filter features a high-flow element that traps contaminants before they reach the injectors, safeguarding critical engine components from premature wear. Its precision-machined housing resists impact and corrosion, while the replaceable filter core makes routine maintenance quick and straightforward. By keeping the fuel stream clean, this filter helps preserve injector performance and overall engine health.
Comprehensive Kit with Precision AN Fittings
Beyond lines and filter, the kit arrives with two screw-together AN fittings for secure attachment to early LS rails, along with assorted hose and adapter fittings for tank and filter connections. Included line clamps and mounting hardware ensure a tidy installation, eliminating the need for additional parts. This complete package streamlines assembly and delivers a professional-grade fuel system ready for any road or track build.
This kit ensures consistent fuel pressure and protection against contamination for your LS swap.
