Ford 5000 Injection Pump Repair

I have a Ford 5000 with a leaking injector pump. The pump works fine and the tractor runs well, however there are a few seals that leak and thus over time the tractor leaks all the fuel out of the tank. Has anyone every tried to repair the seals using one of the injector repair kits (see link below)? I can do most mechanic related things on an engine, but if I feel like I am opening a can of worms (like rebuilding a transmission) I will turn it over to a specialist. Should I attempt to install this repair kit or take it to a shop that specializes in this?

If it has a CAV pump I have pictures of a Massey Ferguson 180 and a 4600 Ford I replaced the throttle shaft seals in.

I have posted a photo of the type of injector pump that is on this tractor. I'm not entirely sure what kind of pump it is?

Anyway.....After getting the tractor up and running it seems as though it isn't leaking any more so there is nothing that needs to be done at this time.

I asked my dad where it was leaking from in the past. He said it was the long hose that goes straight down to just below the oil pan. It looks like this is an overflow line or something? He put a small screw in the bottom of it and now the gas doesn't leak out any more.

Thanks to all for their replies. I am going to use this site a lot more in the future because of the educated responses that I received.

Quoting Removed, click Modern View to see

That long tube is the overflow for the pump sump. It is normal for them to leak there when they have some wear on them and fuel leaks by the plungers into the sump. I expect that the oil in the pump has not been changed. It is supposed to be drained and changed every time the crankcase oil is changed using the same oil as in the crankcase. with new oil it won't leak for awhile, unless your pressure is turned way up. The fill hole is the 7/8 plug on top near the front, the leel plug is the one just to the right of the charge pump and the drain is on the bottom nearly below the level plug. The pump is a Simms in line, and take the screw out so the excess fuel can leak out and tell you when to change the oil again!

soundguy - thanks so much for the super quick response. You posed some good questions for which I dont currently have any answers. I am trying to help my dad out with this repair and he is more familiar with the leaks than I am. I'm going to head over to the farm and get the tractor running today or tomorrow and will post responses to your questions as soon as I have them.

Thanks again!

If the tractor has a CAV rotary pump.... where is it leaking? If it's just on the throttle shaft and shutoff shaft... those are pretty basic nitrile o-rings and they can be replaced fairly easily by removing the cover from the pump.
That said... most 5000's had a Simms inline pump and that kit is of no use to that pump. If yours has the CAV pump it must be a 1975...

are you saying that this is an exterior leak, and will drain the tank.

( but does not fill the crankcase )

does it only leak when setting, or only when running.. or both
