[C320-list] Fuel Control Device

[Michael Paris]

On the Yanmar 3GM30F “Fuel Control Device,” there is a braided wire (not electrical) that goes from one cap screw (to the left of the fuel injector and to the right of the throttle lever) to another cap screw that is about 5 inches below it. Can anyone explain what this set-up is for? I’ve attached a photo but I don’t think photos can be posted here.

I had a slight leak from the upper screw and replaced the copper gasket. I need to replace the wire to do this.

Thanks,
Mike P
