Fuel System Line Kits

Three-Layer Construction: Our fuel lines are constructed with a triple-layer material for unparalleled performance and protection. The innermost layer is made of PTFE for maximum chemical resistance, a braided stainless steel layer for strength and durability, and an outer nylon layer for added abrasion resistance and protection.

Multiple Sizes: We offer our fuel lines in 4AN, 6AN, 8AN, and 10AN sizes, catering to the diverse needs of various fuel delivery systems.

Fitting Types: Our kit includes a variety of fittings at 0°, 90°, 45°, and 180° angles, ensuring versatility and flexibility during installation, allowing for custom routing in tight or complex spaces.

Precision Fit and Leak-Free Performance: The combination of the PTFE inner layer and the high-quality aluminum hose ends ensures a precision fit and leak-free connection, even under extreme pressure, providing a safe and reliable fuel system.
