MF135 diesel. I am leaking fuel out of the injector pump
where the housing that holds the fuel inlet line and line to the
number 3 injector leaves the pump.

Can this be repaired without removing the injector pump?

Might try two new banjo washers, 5936 332C. Leak might also be the head to housing O ring, those start leaking over time too. If the banjo washers don't stop the leak it's best in the long run to remove the pump for a complete re-seal repair.

I have been seeing more of the head to housing O rings starting to leak, still not bad considering these pumps are over 40+ years old!
 
If the washers won't fix the leak then it's the o ring, that's been my experience. That o ring leak will make look just like the washers are leaking.
