3616 HST dies

I recently bought a lightly used 2014 3616 HST. I was told it has died before for apparently no reason but he implied he thought it was fuel supply, maybe some bad fuel. Sure enough, it did it to me after starting and running fine for 15-30 minutes. I tracked it down to running out of fuel and nothing coming out of the gas tank.

I took the gas tank out to flush it and found some lumps of something resembling a turd. Also, the fill strainer basket was floating around in the tank. I thoroughly cleaned the tank, installed all new fuel lines, air filters, fuel filter and it started right up. I went out to do some mowing and it stalled again just like the last time before I cleaned up the fuel system. What I didn’t do was blow out or clean up the fuel injection system.

This is starting to feel like a bad joke.

Oops, first post, double post.
 
I would suggest you NOT fool with the "fuel injection system". That's not homeowner friendly, and most likely not part of the problem. If the engine dies as described it PROBABLY is from lack of fuel. What are you doing to get it going again? Are you finding air in the system AT the injection pump? You have an electric pump that should bleed the system. Is there a bleed screw in the banjo bolt at the injection pump or are you loosening the banjo bolt to bleed it out? You might consider removing the fuel line from tank to filter base and inspecting the inlet fitting on the filter base. That's a good place for foreign material to get lodged.
 
As I said before, I throughly went through the fuel system, tank and fuel lines, up to the injection pump. So I decided to go back and check what I did starting with the fuel supply from the tank. To do that I took the fuel filter cup off and opened the fuel feed valve and it’s flowing good and clean.

I took a closer look at the new fuel filter itself and questioned the installation in my mind. When I installed it, I replaced it how I found it. The hole in the end of the filter down, over the peg in the bottom of the cup. Seemed logical. But, this time I noticed that the hole in the filter had an o-ring in it. The o-ring is obviously in there for a reason so I looked closer up into the fuel filter mount and there was the post. The filter pressed right on and hung there. The filter was in Backwards! No wonder the guy sold it. Between the clogged tank and mis-installed filter, he must have been having a lot more issues with it stalling than he told me. It did run long enough to load it on the flatbed and off when I got home.

I got a swinging deal on the tractor though, 2014 3616 HST with 600 hrs., always stored indoors, it looks new. It came with a box scraper, mower, power tiller and forks. These anttachments are worth $4k new and these are only lightly used. I paid $10k cash but had to drive 4hrs away to flat bed it home, in the rain. The only thing it doesn’t have is a backhoe. I would need to buy a 3-point because it’s not setup for a frame mount. This is the main reason the man sold it. He’d just bought a larger, newer Kubota with backhoe and all new larger attachment bundle deal.
