Good day all, new poster here.
Last year I my M9000 circa early 2000's suffered a clogged fuel filter from bio-diesel and limited use. Someone else has been working our orchard so I've not used the Kubota all that much. While using it, the engine sputtered to a stop and found the fuel filter full of thick gunk from what I gather is caused by bio-diesel garbage they put in the fuel in Kaliphornia. To date (shows that I'm not in a real hurry), been almost a year now. I've changed the filter, cleaned out both tanks, replaced fuel lines that were too old and brittle. Cleaned out the filter housing, water separator, replaced the fuel level sensor. I've blown air through the house towards the tank to ensure it is fully clear and flowing. (low pressure).
So now I am having trouble purging the air out of the system. I've opened the small valve on the fuel distribution module that feeds the individual cylinders. Then use the pump on top of the fuel filter housing. The pump itself goes down easily, but is slow to return to the top. (Could it still be plugged up inside?). I was not able to fully disassemble this unit, the Phillips screw on the handle just turns and found no way to get a look inside completely.
Would an electric fuel pump help in this situation? Since the tanks sit below the running boards....can't gravity feed the fuel like some tractors. I did use a syringe and feed some fuel directly to the distribution module and it ran briefly.
Sorry for the long winded convoluted post. Not an expert by any means on diesels, although I want to learn.
