I am going to install my rebuilt fuel pump with a new push rod. I think it's a little hard to work all the way back in the engine bay so I would appreciate some suggestions for the best way to install the pump. My plan was to start with the push rod and then mount the fuel pump stand to the intake manifold. I dont know if I need to turn the engine by hand to get the push rod as low as possible before I bolt the stand to the manifold.
Is this the right procedure or is it better to mount everything together ( pump, stand and push rod) on the bench and just slide the push rod down and then mount the piece to the intake manifold? Thanks!!

A retired mechanic neighbor said to me about my truck- "Just because they're old, doesn't mean they're easy to work on..."
I tried a bunch of different ways. What worked was taking the fuel pump apart. I put a small C clamp holding the rocker part squeezed while I bolted it all down. Then the 8 little screws holding the two pieces together. Interestingly, the push rod had a big glob of brass welded on the end that contacts the fuel pump rocker.
1Piece, it seems your arm was missing the cup that captures the pushrod. I've had no issues installing the fuel pump by having the push rod, adapter housing installed first, and then just capturing the push rod in the cup of the fuel pump arm while positioning it for bolting. There is absolutely no need to open the fuel pump and separate it and potentially disturb the innards.
I thought that's how it was going to go back together, too. The pump rocker has the cup, and looks like all the pics I've seen. The quarter of an inch of brass added to the end of the push rod looks like a DIY fix instead of replacing a worn pushrod with a new one. It's been shaped to match the diameter of the pushrod to fit the cup on the end of the rocker. I tried rotating the motor to get the pushrod all the way down. I tried pulling the fuelpump stand, etc. I guess the combination of trying to align everything and start the nuts on the studs and hold it all together while leaning across the fender and working around the oil filter, all the while fighting the rocker spring...? I gave up and took the fuel pump apart. I removed it originally bc the bowl was full of crud and the cork seal was leaking. I don't -think- I damaged anything, the diaphragm looked ok as well as the check valves. The two halves did go back together very easily, but "time will tell"...famous last words lol
Funny the OP had this trouble coincidentally as I did. Good luck Mats !
I just needed some advice because I have a bad back and with this kind of work in my engine bay I have to work for 5 minutes and rest for 15!!!
I couldn't figure out if I need to turn the engine by hand or not to move the push rod and I still dont know if I want it in the low or high position. Still waiting for a fuel line but will install next week. Thanks a lot both of you!!!!

From my experience, I have not needed to rotate the engine to specifically position the push rod. However, there is no harm in doing so if you find that it helps you.
