FASS FL1002P50 1/2 in. Push-Lok Replacement Diesel Fuel Line 50 ft.

The FASS FL1002P50 is a genuine 50-foot loop of 1/2-inch inner diameter Push-Lok replacement fuel line, engineered specifically for use with FASS Fuel Air Separation Systems. Constructed from synthetic rubber with a thermoplastic barrier, this hose is built to handle the demands of high-performance diesel fuel delivery while meeting strict environmental and safety standards.

Push-Lok technology allows the line to create a secure, leak-free seal directly onto compatible fittings without the need for clamps, making replacement straightforward and clean. The 50-foot length provides ample material to fully replace all fuel line runs on most FASS system installations.
