Fuel and fluid compatibility

Designed for use with fuel systems, E85, E10, methanol, oils, lubricants, coolant systems, and low-pressure brake/clutch reservoir lines. Note: due to unknown additives in some fuels, we cannot guarantee rubber hose compatibility with all fuels unless stated otherwise. For EFI fuel systems and oiling systems, clamps MUST be used to secure hose ends. Not suitable for submersible applications using unleaded fuels. Not for use with power steering or transmission & oil cooler lines. For fuels outside this specification, Aeroflow's PTFE series hose is recommended.

Installation and safety

• Ensure clamps are used to secure ends on oiling and EFI fuel systems.
• Avoid submersion in unleaded fuels; this hose is not designed for that application.

Performance-ready for longer routes

With a 7.5 metre length, this hose simplifies routing in tight engine bays and across performance builds, reducing clutter while maintaining reliable fuel and fluid delivery. The push-lock design enables quick, secure connections when paired with compatible fittings, making it a practical choice for enthusiasts who value both speed and dependability in their fuel and fluid lines.
