Use a bolt with tight tolerance in the bearing hole. Keep adding grease and tapping bolt. The bearing will come out.
I'll try explaining this again....
If you look behind the pilot bearing on a F20 crank, there is a rather large hole center drilled in the crank, it goes all the way through into the crankcase. There is a felt wick in this hole that brings oil from inside the crankcase to oil the pilot bearing, which is sealed on just the outside. That felt just swells up and stays in there. Nothing holds it. There is no way your method will work on a F series engine, all the pressure your trying to build will just force the wick into the crankcase and Curt will end up with a huge mess inside his engine and still need an internal puller. While it may be a great technique for other engines it does not apply here.
I am adding a pic of a F30 pilot bearing/ rear seal, I have the wick removed and if you look through the bearing you can see half of the oil hole,its big. You can also see the original bearing that is sealed on the outside and open on the inside.
