Kubota l175 not getting fuel

Start at the beginning. Check if you are getting fuel to the filter. Mine have gotten gummed up at various times recently. If you are getting fuel to and through the filter, crack your bleeder screw until you get a good stream with no bubbles. After that you will know that you are getting fuel to the injector pump. Crack the nuts for the injector supply lines loose and give it a crank to see if you are getting fuel. Use the de-comp lever and avoid overcranking so you do not burn up your starter. Once you get fuel leaking from the supply lines tighten them down and fire her up. If you are not getting fuel through the pump, you will have bigger (e.g. much more expensive) issues.
There is a fuel shutoff valve under the forward left corner of the tank, check to make sure someone hasn't closed it.
Hopefully it is only a closed valve or clogged filter.

It started fine one day, ran good. A few days later I went to start it and it would not start. I found that I wasn't getting fuel and changed the fuel filter, drained the tank, changed the fuel lines. Added new fuel, bled the lines. OUt of the injector pump, one will squirt but the other one just bubbles a little bit and I can't get the fuel to come out of it. The old fuel filter had trash in it.
It sounds like an air bubble in that pump piston but could be a bit of gunk clogging the feed passage in the pump. Before opening it up you might try cracking both injector lines at the pump, pulling the compression release, opening the throttle to full, and giving it a couple of good long cranks. Be sure not to overheat the starter.
I'd remove the fuel inlet elbow off the pump and check that before opening the pump. If you do open it up be sure not to get the pistons and other parts mixed up between pump cylinders. You also need to be careful not to get any dust or dirt in the pump. I throughly flushed and washed all the parts with brake cleaner before I put it back together.

As Stumpy says, remove the injector lines at the outlet of the pump. release the compression release, and crank. Make sure the issue is with the pump, not a clogged, or bad injector. When you see good squirting at each injector pump discharge then reattach the lines, and then crack them at the injector end. Do it again. Make sure the fuel is getting out of each line. then, reattach to the injectors. If you have done all this fuel line replacing, it is likely there is a fuel/air bubble somewhere. Removing the fuel lines to the injector is key to getting all the air out. Don't ask me how I know...... 
I have an old B6000. One thing I have learned is: never, NEVER EVER let it run out of fuel.....
