I am not sure what you are calling gunk but if this gunk is black it is engine oil. The tractor and the engine was built by Yanmar. The injection pump is lubricated with oil pressure from the engine. The seals in the pump will leak and engine oil will get in the fuel system and contaminate the diesel fuel and plug the fuel. Seals will have to be replaced in the injection pump to correct the gunk.
If you removed your injector lines, and then reattached them. You first off got air in the line and you will have to purge them. But, I believe that your injector gasket was probably the culprit and why it was leaking. It sounds like the injector was losing fuel pressure and the pump was unable the push enough fuel to all the cylinders when under load.
If it were me, I would go online to HoyteTractors.com they carry every part for your Yanmar tractor that you will ever need. They also have a tech department too. Since you already have air in your lines, you might as well replace the fuel filter and O-ring and injectors seals. You can also get a service manual from Hoyte for your specific tractor model. If your Yanmar (3000) is like mine, my fuel pump is on the "passenger side" of the tractor and it has a bleed valve on it. So after you replace your parts you can bleed the air out. They are very simple machines to work on. Just in case you didnt know, most Yanmar tractors are a direct cross to John Deere Tractor Models. Any John Deere tractor under 100hp is/was Mfg. by Yanmar for 30-40 yrs or so. Good Luck!!
I found the tech manual one lin but it can"t be opened since deere is updating it.I will see if we have the book"tm1974" at the dealership in the morning and get back to you.
