350D Injecter Pump

I started and ran dad's old 350D for awhile Saturday. Had not run it all that much since he died.
Among the many leaks the old tractor has, it has a leak in the injecter pump when you shut it down. It will drain the pump if it sets for any period of time. I have been shutting the fuel off at the tank so it does not make a mess.
Can I put in an o-ring set or something to fix it, or must it go to an injecter pump type to fix it?
Don't know if I want to put a lot of money in it or not.
 
Bill its over 10 years since I had one. Will put what i think I remember, maybe someone with a fresher memory will post. After the pump is removed the drive shaft will pull out or may come out when pump is removed. Seals can be replaced on the shaft. Shaft has a place on it to match the inside when putting it back, make sure they line up. Under the pump theres a adapter that is turned to adjust the drive gear play, O ring under it and another on top. If no engine oil is leaking out and gear play is okay don't remove the adapter. If drive shaft under pump is left in place the pump shaft will only go back in the same gear time. If pump drive is removed put the slots back in the same direction.
Best to remove the timing window on pump first and turn engine until marks are lined up, then do not move engine anymore and line marks back up when installing.
 
I knew about the timing marks. I worked on Roosa Master pumps when I was in the Army. We had them on generators.
I can't tell exactly where the fuel is coming from. I guess I need to clean it all up and try and find where it is leaking.
Sure hate to take it to a shop for something simple. It runs like a bandit when running. Sure hate to mess it up.
