I almost didn’t see this because it wasn’t in the bulldozer section. The moderator would have moved your post, but he is mostly non-existent.
So your dozer is actually a Guilin that was rebranded as a Rhino, and Guilin was purchased by Yuchai sometime around 2002. Not many changes overall. A little more info on your machine would be extremely helpful.
Does it have the six-way blade? What was the function of the broken hydraulic hoses? I assume they have the ORFS fittings?
There are quite a few hydraulic hoses listed here, but there are also adapter fittings to convert to JIC fittings so you can make your own hoses.

I ordered a creeper case, and beer.
Ezcellent! Hahahahaha

Thank you. Got a case on the way
A case of what, beer? Or did you buy a Case tractor?

I believe the stock pumps are rated 7 gpm @ 2,200 psig. The flow is dependent on engine speed. Higher capacity pumps are available if there is room to fit them between the housing and starter motor. I don’t think they will fit on the two cylinder engines.
Yeah, with only a ~10 amp draw, you definitely have a bad glow plug.

A fuel biocide treatment is the only thing I know of that is cost effective and safe for all components. There are quite a few in the consumer lines but I recommend Hammond’s Biobor because it is used by the Navy and Air Force, and I have personal first hand experience with it at work treating 100,000 gallon fuel tanks on ships. It is also used at the fuel dock tank farms in Seattle.
That’s why subsequent dosings of fresh fuel and monitoring is recommended after a system clean out to allow the remaining dead bugs to pass through. Yeah, they are pretty nasty and very destructive. Don’t think I would bother with the pipe cleaners and brushes though. We have 1″ hard piped fuel lines everywhere, so that’s not going to happen. We also centrifuge our fuel but even that doen’t get them all.

Only problem with using compressed air to blow out the tank is that it too contains a lot of moisture, unless you have an air dryer system. I would still use the heat lamps, regardless.

Unfortunately yes, the bugs will pass through a filter. It’s when the filters are overcome that they begin to back up and clog. These are microscopic, so when you see sludge that means there are literally zillions of them. And yes, the fuel lines should be flushed and cleaned as well. After everything is cleaned and reinstalled on the tractor, the fresh fuel must still be treated with the biocide for at least two tankfuls, and monitored (for at least as long, to make sure they haven’t reoccurred). Kind of a time consuming and expensive process, but it’s a lesson learned, and it’s still cheaper than replacing a fuel injection pump and a set of injectors.

Cal, with these small tanks it’s best if you can remove them to clean them. Best way is to use a sewer cleaning tip with your pressure washer, with all tank hoses and fittings removed. That’s as close to Butterworthing as you can get inexpensively. Next best would be a high pressure spray from a garden hose with the tank upside down until you get clear water coming from the fill pipe. After that, turn the tank right side up and apply heat lamps for as long as it takes to thoroughly heat the tank and evaporate any moisture. You will need to change your spin on filter because you found bugs in it. Remember, they are very corrosive. In my case I found they badly pitted the valve seats in my lift/priming pump to the point where it wouldn’t pump at all – had to replace the pump (I have since removed the manual lift/priming pump and replaced with an electric pump).
