Here's a little tool I made to move the pump with the lines attached. The black bolt should be longer, this was just for a test. If you had the skill it could also be made with pins instead of bolts.
And in use.
If you need any specs on it, just ask. It's pretty self explanitory.
How did you put force on the rod? With an engine hoist?
