When I stripped down the engine to send to the builder, I couldn't get the push rod out. As it turns out it was mushroomed on the end and had to be filed down in order to remove. The spring in the fuel pump may be getting tired as well no longer keeping the rod in intimate contact with the cam. I would remove and replace pump and rod if it shows signs or wear.

Avoid the comp cams hollow pushrod(steel tip), had one go south in less than 2k. ARP hollow(steel tip) worked good and I put one of the total composites in last time I had it apart to try, but have yet to put any miles on it.
