CM2350 Fuel Pump Rebuild Help

[Golfnut]

I'm beginning to think I bit off more than I can chew with this one. I got the rebuild parts from and have some time so I started this project today. I was under the impression I could remove the head of the fuel pump without removing the pump from the truck. Am I wrong on this? I've got the fuel lines removed but can't get at the electrical connection and also can't get to the tappet guide pin plugs. Unfortunately I'm at a point where can't turn back but the truck is in my heated shop. I may have to get someone to help me.
