to remove the pump could i jus unscrew the oil fill tube and take the nut off that way? or do i have to pull the whole gear cover off? and will the pump gear jus stay in place once i pull the pump?

The idea behind the gear is that it simply rests on top the cam gear and sets inside/against the innards of the gear case. However, it seems to be a problem for many that it falls out of position. I honestly don't know what folks are doing, but it seems it moves a round in there and then find out the pump timing is a gear or more off.
If you leave it well enough alone it will not jump a tooth. Seriously, it won't. Just don't get rough with it and leave it be. It will remain in time.
Make sure you turn (bar) the engine so the gear's key way is about 2:00 position. You may need a mirror to see the very edge of it but it's visable with a strong light and a good eye, even w/the nut in place.

With the engine at #1 TDC compression, the pump and engine are timed together. Yet, that puts that key/key way at the bottom. We really don't want that to fall out and down/into the case. So, 12:00 would work better, but with that, the key way is a bit tougher to see and the pump is sometimes turned a bit to the side so 12:00 really isn't thet top. 2:00 is. Its easy to see at the 2 position and the key will not fall. But, anything works better then at the bottom.
The engine and the pump don't have to be at their own TDC #1 position because the pump is keyed to the engine. It goes on only ONE WAY.

Wow. Did you manage to sheer the key off or push it out and into the timing case?
I sent a pump back to a fellow in Southern Cal who e-mailed me information about the bum pump work, only turned oiut to be he too installed the pump wrong. sheering off the key when he jammed the gear back onto the pump drive.
It's gotta be right on when the pump is slid onto the mounting studs and at the same time I hold/slide the gear onto the shaft. The puller bolts can be reinstalled into the gear hub to provide a hand hold to manipulate and index the gear onto the drive shaft.
