You do have to reach underneath it quite a bit to get them all loose but keep in mind, once you have the first set off then getting to the remaining 3 towards the block will be easy. Also, if you're just replacing the pump you don't have to completely remove the back set of lines, just take the clamps loose from the intake, take the line nuts off the back of the pump and push them out of the way when you're ready to pull the pump. If you do it that way then you don't have to loosen the line nuts on the head back on #5 and #6. Makes it go quite a bit faster. The first 3 or 4 I did I took everything off but I keep doing less and less every time. I'm down to about 56 mins for a VP swap.
