When i ground my fuel pin, I lubed it up with What ever dad had in the grease gun at the farm. Probably soy grease. Mine has never had a problem. I also shaved my washer alittle too. The previous owner was a diesel mechanic at a dodge dealer and he put an injector pump on this truck before i got it. When i went to adjust the starwheel the first time it was a 1/4 turn from bottoming out. I found that percular being that the rest of the pump had never be "molested"! haha
