I am assuming that the L200 is similar to the L185 and is fairly old...

There are a few things that you need to check.

Assuming you’re fuel filter is lower than the fuel tank, take the fuel line off at the inlet to the injection pump to be sure you have good fuel flow to the pump. Put a bucket under to catch the fuel. If the filter was empty when installed it may need to have an escape for the air to exit and this will let that happen and prove you have fuel flow to the pump.

If you don’t have fuel flow then move towards the tank to find out where you do have fuel flow. There should be a line into the fuel filter that would be the next place to check.

If yo do have fuel flow then put the line back onto the injection pump and open the valve at the injection pump, it is the bolt that you spoke of. That will get all the air out of the lines to the injection pump. You do not need to crank the tractor for any of these checks. Tighten the valve, holding the larger hexagonal fitting behind the bolt head valve.

Then put the throttle all the way to high rpm setting. Then crack open the fuel lines at the top of the injectors by loosening the nuts about a half to full turn. Then crank the tractor (hold open the decompression knob if you have one) in 5 to 10 second operation with a good minute rest between cranks to allow the starter to cool down. Don’t crank too many times without letting the starter cool off for a long time. You should see fuel and air bubbles coming out at the injector line fittings. When you see only fuel, then tighten up the fitting on the injector. When all are done then try to start the tractor by holding the glow plugs on for about 30 seconds, holding out the decompression knob and cranking the tractor. When the engine is spinning fast, push the decompression knob in and it should start!

There is also an article about this on this forum, but you may have to be on the website (not Tapatalk or similar) to see it.

Thanks Mr. King..........

Yes the L200 was the first model Kubota shipped to the USA........ Some were gray market written in Japanese........ Mine was made for the USA market and is in English......... Very hard to find parts for it.......... I found that a certain John Deere starter will fit it (Cheaper than an aftermarket for the L200).........

I will go through all of the steps again........ Maybe I missed something.........What do you mean (Tighten the valve, holding the larger hexagonal fitting behind the bolt head valve.)???

Previous owner showed me a crack on a part of the fuel filter housing..... He said it was there when he got it and had been running fine...... (It is not leaking fuel from the crack)........ I was thinking he didn't seat the O-ring/gasket correctly when he changed the fuel filter and it may be sucking in air from there........

Thanks again from ALABAMA.......... DCS .........

My memory may be bad on this since I haven’t really looked at this in a while. But on my injection pump, where the fuel line attaches, is an arrangement of hexagonal fittings with the top looking like a bolt head. If you try to turn the top bolt the lower fittings will sometimes try to rotate along with the bolt head. Using a open ended wrench on the lower hex fitting keeps it from rotating.

The top hex bolt is the valve that allows the air to bleed out of the line to the injection pump (if memory is good).
