Fighting what I think is a fuel issue

[ruffdog]

I use my Pela 650 oil extractor to drain oil/fuel. It has been very useful.

Just drain the tank, at the fuel line before it goes into fuel filter. Catch it all in plastic containers. Safety is a priority. Then likewise pull the fuel filter and replace with a new filter. Prime or fill that new filter with clean diesel prior to installing it. Evaluate the drained diesel for any sediment, solids, algae and water. Then reattach the fuel line to fuel filter, and fill the tank.

And if the debris is larger than the outlet, which I would expect, you haven't solved the problem. I don't know the tractor at all, but if it's not a huge deal to pull the tank and clean it, that's what I would do. If it's a big job, then I would look at rigging a jug to the rops or something where you can feed it fuel from a new source and then put it to work and see if that fixes the issue. If it still does it, then you know debris in the tank probably isn't the issue.

Neighbor's Allis WD tractor would randomly quit too. His fuel tank and filter was SPOTLESS....except for a small piece of brass shim stock that would move around until it plugged the outlet. The point is, the OP has to look for that ONE thing that may be plugging the tank outlet and get it out.

Blow air backwards into the tank so as to clear any debris that might block the strainer.
If that improves the situation for a while you would have confirmed the cause.
Next step would be a tank cleaning.

For that reason I always double filter my fuel when filling.

My other precaution is to always add an anti gelling dose to every fueling operation as I have gelled a few times and that's no fun.
You simply can not be sure if the fuel is not leftover summer fuel, like especially now since I just laid in my winter needs and conceivably it is st ill summer fuel.

I fill from a holding tank that has a 10 micron filter on the outlet

Bugs are good ones to block tank outlets. First, they may crawl up into your unfiltered nozzle opening and die there. Then, the next time you fill, you deposit Mr. bug right into your tank. That is why I at least shake out the nozzle before I insert it in the filler hole.

Is your hydraulic fluid level okay?

I would suspect debris in the tank restricting the fuel outlet. Gets sucked to the fuel outlet when the engine is running, floats away when the engine is not running.

i totally agree. i had the same issue with my zero turn. it would run fine then start to shut down. found a leaf or two had gotten into the tank and would settle down when not in use then get sucked up on the end of the fuel line until it shut down. drain your tank

And you got leaves to come out the tank outlet when you drained it? I've heard of plastic drill shaving found in tanks causing issues like this. That's why I would pull the tank and clean. Not likely you are going to drain the problem out through the outlet.
