    I am replacing my mechanical fuel pump and after removing the old one, the push rod that operates the pump lever slid down to block the opening. What is the trick to getting the pump push rod back into place so you can slide the pump lever in the slot and bolt it on?

    Get a gob of grease on the end of thr rod and slide it in......the grease will keep it from sliding out.

    You can also use a hacksaw blade to hold it up while you slide it in.

    A hacksaw blade works pretty well for holding it up in place. Also, for future reference, look at the front of the block on the passenger side. There are two bolt holes, one above the other. The top one should have a short 3/8 bolt in it. Before removing the old pump, pull this short bolt and thread in a longer one until it bottoms out. Now when you take the pump off this bolt will hold the pushrod up. Just be sure to remove the long bolt and replace it with the short one before you fire it up.
