255 LPH Fuel Line and Regulator Kit for LS Engine Swaps
When an LS engine swap demands precise fuel pressure the Fuel Line and Regulator Kit - 255 LPH provides a supply system designed for returnless LS and LT fuel rail setups. This assembly features a P.T.F.E. inner tube wrapped in a stainless steel braid with a black protective jacket to prevent abrasion and guard adjacent chassis or wiring. The integrated filter and regulator is preset to 58 psi to meet GM LS specs while two piece screw together fittings at the rail and regulator outlet simplify plumbing. Assorted AN style connectors adapt lines from any 255 LPH in tank pump and included clamps and mounting hardware ensure secure installation. Manufactured in the USA from corrosion resistant materials this kit provides reliable pressure control and long service life.
Durable Stainless Steel Supply Line
The Fuel Line and Regulator Kit features a PTFE core inside a stainless steel braided line wrapped in a black protective jacket. PTFE offers exceptional resistance to fuel blends and temperature extremes, while the steel braid resists abrasion and retains shape under vibration. The protective jacketing prevents chafing against frame rails or engine components. Stainless steel construction provides inherent corrosion resistance, critical in high-humidity or road-debris environments. Craftsmanship in the USA ensures each assembly meets strict dimensional and material specifications for reliable long-term service.
Integrated Fuel Pressure Regulation
At the heart of the kit is an OE-style fuel filter combined with a pressure regulator preset to 58 psi. This configuration ensures precise fuel metering for LS engines, producing consistent spray patterns and efficient combustion. The diaphragm-based regulator employs factory calibration to maintain steady output under transient load changes, eliminating the need for manual adjustment gauges. A stainless steel housing encloses a high-flow filter element that captures particles before they reach the injectors. The integrated design mounts directly to the supply line, reducing the number of fittings and possible leak paths.
Simplified Installation and Compatibility
The returnless design accommodates modern LS and LT fuel rails without requiring a separate return line to the tank. Installers benefit from fewer hoses, streamlined routing, and lower plumbing costs. Precision-engineered aluminum fittings resist corrosion and seal under high pressure, speeding up assembly and minimizing maintenance. Uniform material selection and straightforward routing make this kit a complete solution for custom LS engine installations.
The 255 LPH kit uses a PTFE inner tube with stainless braid and an integrated 58 psi filter regulator to meet GM LS fuel requirements. To step up your supply with the same kit but at a higher capacity of 400 LPH consider our Fuel Line and Regulator Kit - 400 LPH.
