Start at the injection pump,make sure the fuel is getting from the tank to the injection pump, back off the nuts on the top of the injection pump that hold the injector lines, make sure the fuel is coming out of the backed off nuts as you can crank it over.
At the other end of your injection pipes, which are connected to your injectors, back off thse nuts as well, and cranking the motor over make sure all the air is out of those lines before tightening the nuts.
The filters are self explanatory, undo the bleed nut on the top of the filter housing and get all the air bubbles out. That is usually done with the weight of the fuel that is in the tank. ie'. gravity. Just remember a diesel will not run if it has the slighest amount of air in the fuel system.
It sounds more complicated than it is,it really its basic,
Keep your fuel exceptionally clean, I can't emphasise that point enough.
That should get the Massey running if the motor is in good condition, ie: good compression, that's what a diesel depends on, ie: 16/1 as compared to a petrol motor of 6/1.
Cheers.

Some things I have learned bleeding diesel fuel systems. If needed install new fuel filters before you begin. Check the lift pump if you have one. It can have a fuel strainer that can collect trash so it needs to be cleaned. As stated loosen the connections and pump fuel through the system, a lift pump that has a manual pumping lever is your friend. Use it to save your battery as much as possible. Lots of cranking can weaken it quickly. Finally if you have a fuel shutoff valve between the tank and lift pump, make sure it is on. That will help too. Trying to bleed a system is very difficult with it closed. I know from experience.

You have a very rare tractor. It's my understanding there were less than 200 model 33s fitted with a diesel engine.
Keep us updated on your progress if you get a chance. We'd like to know how it turns out.
