I have a TO-35 with the Standard 23 diesel. The fuel tank was leaking so I took it to a radiator shop and had it cleaned and repaired. While the tank was off, I changed the fuel filters. The tractor now will not run. It got it to run twice for about 20 seconds and then it starved out for fuel. I have had the tractor run out of fuel in the past and have not had any problems getting it going again. I am at a lost right now. Any ideas?

My first thought would be that you got some air in the fuel system when you changed the filters. You need to check to see if you are getting fuel to the injector pump. Crack the fuel inlet line at the pump and crank the engine to see if fuel is there. If not, you have air or obstruction prior to the injection pump, so work back checking the fuel lines at both sides of the filter, the supply pump, and the fuel bowl. If there is fuel at the injection pump, see if there is fuel or air leaving the pump by barely loosening each of the injector fuel line caps, one at a time, as they leave the pump while cranking the engine. If there is air bubbling out, you have air in the system. If fuel is coming out there, crack or loosen each of the injector fuel lines at the injectors, one at a time starting with the injector closest to the pump. Cracking the lines tells you if there is fuel in the system, air in the pump or lines, and also serves to bleed the air out if you do it in a manner that goes from fuel tank to the injectors. All of this should help you narrow down the problem! Good luck.

I don't know what the fuel filters are like on the Standard diesel, but some diesel filters like those used on the Ford tractors have fuel inlets only around the outer edge and if you put the wrong o-ring gasket in it will block fuel flow. Just something to check...

Here is what I am talking about where the wrong gasket can block fuel flow on a Napa or WIX filter. This was posted by Jim.ME in the Ford forum.
It might push some air out, but remember air will compress, fuel will not. I would put some penetrant on the nuts for a couple of days, and get a six point line wrench to try to break the lines loose, if you don't have one. If you get them off and no air is trapped, next step is taking each injector out and see if they will inject at cranking speed.
