How do you bleed the injectors on a Massey Ferguson tractor?

1. undo the bleed valve on top of the sediment bowl, and pump the primer 10 times

then close the valve.

2. open the bleed valve on the 1rst fuel filter, (top valve) repeat pumping. close valve.

do the same to the bottom valve on the 1rst filter.

3. do the same to the secondary filter.

4. open the valve on the fuel pump(under the injector lines) pump and close it

5. do the same to the bottom valve.

6. if you have four injector fuel lines(four cylinder) undo two lines at a time and turn the key until straight diesel comes out, then reattach line. repeat with other two. then start the tractor.

if it doesn't work, you may have more air in the lines or another problem.
