My new 332 is leaking fuel around the bottom of the injectors where they go into the pump. The middle one is ok, just the outside ones. The arrows show the fuel leaking when I turn the key on. I have read other posts about this problem, and replacing the o-ring and also a copper washer. I have not seen a breakdown of the parts. I would like to know what I am getting into before I remove the injection lines and then the injectors. Is there an o-ring and a copper washer? And should they be replaced with new ones? Does JD store have them? I have loosened the ferrule on top and tried to snug the nut that goes into the pump, but it still leaks. When I do get the washers replaced, do I just loosen the ferrule on top and turn the key on until a good flow of fuel appears so I get the air out? The arrows shows where the fuel is leaking from between the nut and the base. Thanks in advance, the tractor runs great, so I do not want to make a problem worse.
