This is an 81 so it should be the earlier type pump.
My plan was to just pull the oil filter housing for the sake of ease on the pump.
I assumed the bottom plate was like the bottom plate on the 603

Yes, the IP front Gasket is Paper.
On my 84 300D the Fuel Injection Pump has a Plug that you would need a 17mm wrench to remove.
I have a Pump from a 78 300SD and I believe it takes a 14mm wrench to remove the Plug. But, for sure it is smaller than 17mm.
Unless the old Bottom Plate O-ring on the Fuel Injection Pump is just crumbling away I do not see why careful use of Silicon Sealant would not seal it if you removed the O-ring and put the Silicon between the Plate and the O-ring and put some on the sealing area where it seals to the Fuel Injection Pump.
The Oil in that area enters the IP Housing under pressure but once inside it is not under pressure. The sump acts as a reservoir and the action of the moving parts splashes the Oil around.
The 603 is an M type Pump and I have only seen the pictures that People have posted.
