Positioning the seat correctly makes a relatively easy and comfortable position to work in.
Also, a set of metric flare wrenches made all the difference in the world screwing the hoses back in.
I just reread your first post. I had no trouble with the flare wrenches on any of the hoses. If you do you may want to take a grinder to the neck and grind it down to make more room to turn the nut.

TIP: do the top hoses first then the lower hoses. You don't want to run the risk of dropping an o-ring into the valve before it can seat properly.
Don't ask how I know this.
