Choose hose for the exact application

Match the hose size to the connection and check Gates' current specifications for the exact part number against your fuel type and blend, system working pressure and operating temperature. Do not assume that an MPI designation makes the hose suitable for every fuel system, direct-injection pressure circuit or installation inside a fuel tank.

For petrol, diesel, ethanol blends such as E85, methanol or biodiesel, confirm the permitted fuel and concentration in the part-specific Gates documentation before ordering. Check any restrictions on continuous versus intermittent temperature exposure and submerged use.

Check connections and routing

Use fittings and retention methods specified for this hose and the intended fuel-system pressure. A matching nominal size or AN designation alone does not establish compatibility with a hose end; do not assume suitability for reusable braided-hose fittings or pushlock fittings.

Plan the required length and routing with allowance for movement and the manufacturer's bend requirements. Avoid kinks, abrasion and contact with hot or moving components, and follow the hose and fitting manufacturers' installation instructions.
