Hello Group, I need some help.
I have a 5035HST with 162 hrs that is within a few weeks of being 1 year old. The tractor has been great and no real issues until now. A few hours (operating) back i started to get a fuel leak that appeared to be coming from the area above the tank. It was a few drips here and there at first, then within a use or two was enough to leave a small puddle on the floor. I thought it was just a loose clamp or something along those lines, but they all seems to be tight. After studying it some more it seemed to be a leak in one of the fuel lines itself. This propmted trip #1 to the dealer. Their prognosis was that it was leaking from the connection, not the hose, and they put a new clamp on. I was skeptical, but figured they should know.
After getting it back, about 30 minutes into running it fuel started gushing from under the hood and running out. To put gushing into perspective, I would say on the order of 1 qt in 30 seconds. I noticed that one of the lines on the back of the injectors (low pressure return?) had come off. I pushed it back on and it was ok for another 30 minutes before it blew again. This time I used a cable tie to clamp it back on. That seemed to hold it. After a little more time I had gushing fuel again...back to the dealer.
Dealer prognosis was that the return from the injectors had come off where it goes into the connection by the filter. The thought was that I might have pulled it off when putting the other one back on. I was pretty sure this was not the case has i checked the rest of the lines after the first one blew off. Got it back yesterday and ran it last night for 30 minutes or so and had another gushing but at about half the rate of the previous ones. When I stopped and raised the hood I could not see the exact source of the leak. All drain lines were connected, but I could tell it was coming from high up on the engine, in the neighborhood of the injectors. I double checked all of the connections closed it back up and ran it a bit longer. The rest time was only a couple of minutes. It was ok.
This morning I started on one of my significant projects that would require a few hours of seat time, and lo and behold, gushing. I am not sure exactly how long it had been running, but probably between 30 minutes and 1 hour. This time I left it running while I got the hood up so that I could see where the leak was exactly. I could see two places, one being what I am calling the drain line from the injectors, the other on the fuel pump. The hoses were not blow off the injectors, but it was clearly coming from the line between the front most and the next injector. On the pump the is a braided line that attaches high and to the rear on what I assume is the fuel shut off solenoid. It was leaking at this connection, but it looks more like the line itself than the fitting.
I don't know alot about how a diesel system works. It would seem to me that the return lines from the injectors should be low to no pressure based on the type of tubing they used. If that is the case, should that drain directly back to the tank or does it go through some other component that could cause the restriction? Any idea of where to look? Good guys at the dealer and they are trying, but my confidence level in them isn't real high.
The tractor runs fine during all of this.
Thank you,
Travis
