Hello and welcome to JustAnswer!
The problem could be air being drawn into the system from a leaking line fitting or a pinhole in a line. A pinhole in a return line can draw air into the system but not leak externally.
I'm assuming the problem was there before the rack was replaced. If the problem actually started when the rack was replaced then it would be the most likely cause.
It's definitely possible that the reservoir or the seals between it and the pump are causing air to be drawn into the system.
The pump itself is the most likely cause for this. I've seen dozens of issues with aftermarket pumps, if an aftermarket replacement was installed there is a very good chance it's still the problem.
