Replacement Fuel Line 3/16" ID x 39" Length for Scooters & Mopeds

Replacement Fuel Line for GY6 and 139QMB Scooters

This rubber fuel line has a 3/16" inside diameter and runs 39" long, so it works well for swapping out a cracked or leaking line. It is made to suit GY6 125cc/150cc engines and 50cc 139QMB engines. As part of the scooter fuel system, it carries fuel to the engine so the scooter runs as it should.

Build and Fit Range

Made from flexible rubber, the line holds up against common fuel types and bends enough to route neatly along your scooter's frame. It connects to the standard 5mm fuel barb found on many Chinese and Taiwanese scooter fuel setups, so it suits a wide range of scooter models.

Signs It Needs Replacing

Check fuel lines on a regular schedule for cracks, stiffness, or leaks. A fuel smell or fuel collecting under the scooter means the line should be swapped. A sound fuel line helps the whole scooter fuel system keep working properly.
