All you need is a piece of 1" steel pipe, long enough to reach the pitless, with threads on both ends. On the top end you thread on a 1" tee, with 2 nipples sticking out the sides for a handle. The 1" threads on the bottom should screw right into the pitless half.
When you pull the pitless half up from the stationary part, you are lifting the pipe, wire, pump, and everything at the same time. Just don't let anything hang up on the stationary part of the pitless as you pull it out of the well.
Some pitless units have a cable release. If you don't see a cable, it should just pull straight up and out.
