Here is the cheap obstruction wrench I picked up from Harbor Freight. Worked fine for removing the 3 mounting nuts that hold the pump to the housing.

Here is one of two mounting nuts that needs this wrench. Also don’t forget to plug the fuel line so dirt does not fall in.

Notice the towel tucked into the opening to keep the nut and washer from falling into the housing. It also keeps dirt out that falls from so much activity in the area.

For the very last couple of turns when removing the injection pump to gear nut, I used this telescoping magnet. Worked great!

Removing the washer with a magnet made it very easy. It’s recessed a bit.

I used my steering wheel puller to remove the gear from the pump. The gear is only freed from the shaft but stays in the housing.

Here the fuel lines from the rear of the injection pump are layed down out of the way so the pump can be removed.

No matching mark on the pump flange. You can see the one on the housing.

I originally forgot to remove this fuel fitting as I was trying to pull the pump out.

Always take out the tab and re-tighten the shaft lock down screw. It keeps the shaft from rotating while working on the pump.

I marked the woodruff key location on the housing with 2 scratch marks. This has to be done if the engine is not at top dead center. The internals of the pump have to be aligned to this key during the resealing process.
