Product Description

Fuel Return Line Specifications

The OEM fuel return line, or fuel return tube, is a clear plastic line that returns fuel from the primer bulb back into the fuel tank of your engine. You will know your fuel return line is in need of replacement if cracks or leaks have begun appearing, and fuel is leaking from your carburetor. This part is sold individually, and you will know if it is right for your engine by checking your model number or owners manual. One end of the line will attach to the primer bulb, and the other to the fuel tank; make sure all fuel lines are tight when completing this repair, to prevent leaks and fire hazard risks. Most customers rated this repair as easy.
