I'm slowly working my way through systems on old boat we bought. One of the 3HM35F's has started running rough since the delivery
trip. I had the three injectors tested yesterday, all okay, and reinstalled today. Examined all the hardware
as I put it back on the engine
, and one of the three banjo bolts holding the return fuel
harness to the top of the injectors was really bad. Half way cracked through, with the other half just about to let go.
I can see that fuel
would be going down the crack in the bolt, and getting around the lower copper washer. I can't see that this would hurt anything, other than being a small fuel leak onto the top of the injector. However, I thought I better ask some of you more knowledgeable diesel
Would a slight leak in the fuel return line cause any issues on one of these engines? I can imagine that this is low pressure fuel, so I'm thinking it wouldn't affect anything going on in the engine
