The push rod the arrow points to in your lower photo needs to engage the pump lever indicated by the arrow in the upper photo. You can use grease to hold the push rod up in place as you install the pump or hold the end of the push rod up using sometning like a bent hacksaw blade that is simply pulled out after the pump is in place.
The push rod should contact the pump lever on the side opposite the arrow in the upper photo...
Thanks.. been reading up. if it is resting fully down as it is... just a hacksaw or screw driver should freely slide it up? I tried to bump it up with a screw driver an hour ago and it seemed solid - now that i expect it to move up i need to try again.
There is a short bolt on the front of the block where that push rod lines up. It’s basically just a plug. You can remove that bolt, replace it with a longer one then tighten it to hold the push rod up against the cam. Then install the fuel pump and swap back to the short plug bolt and the push rod will drop down against the fuel pump actuator arm.

Here is what you need to do:
Find the #1 plug wire on your distributor cap and make note of the position of the #1 tower.
Pop the distributor cap off and then "bump" the engine over (using the starter) until the rotor points to the #1 tower position.
Put the cap back on
Remove the plug bolt from the front of the engine block for the fuel pump pushrod hole location:
Using your fingers, needle nosed pliers, or a screwdriver, push the fuel pump pushrod upwards until it hits the camshaft eccentric. It should move upwards about an inch from its current "dropped-down" position. Hold it there.
Install a fully-threaded 2" long bolt into the hole that you pulled the plug bolt out of. Tighten the bolt until you feel it hitting and jamming the pushrod.
Install your new fuel pump and snug it down.
Remove the 2" long jam bolt and re-install the stock plug bolt.
What Lars said plus this. Take a piece of cardboard and with a felt pen write:
SWAP BOLT BEFORE STARTING !
Place that sign where ever its needed. If you forget about the bolt, you will ruin the pushrod, destroy the fuelpump and likely damage the camshaft.
Also, you are just two bolts away from stopping a common oil leak. The fuelpump mounting plate. The gasket is only a buck, takes five minutes to remove, clean, Permatex Black, bolts back on.

That's a sweet-*** workshop floor. I'll bet you don't walk too fast on that floor with snow on the soles of your shoes... (not that I think you know what snow is...)

Thanks guys. I realize i am soooooo lucky. This is part of my "for ever" home. As a DIY job it took many weekend sprints and my knees still hurt. The perimiter last row is still not done. You guys are so helpful!
