No Longer Available
Return Grommet
Part #6697846
This individually sold grommet is a genuine OEM part and is used for a variety of different small engine/outdoor lawn equipment. The return fuel line from the carburetor is installed through this grommet, which creates a seal to prevent future leaks and ignition issues. Over time and through exposure to fuel, the grommet can wear down, leading to cracks, tears, and missing pieces. If you notice fuel is leaking during operation, or are having issues with starting the engine, this grommet may be the cause. Depending on your model, installing the return line in the grommet and then installing both together in the fuel tank may be easiest, rather than installing them separately.
