I bought a [https://www.amazon.com/gp/product/B00B8KBVZE/ref=oh_aui_detailpage_o00_s00|new pump from Amazon] (Ulka EX5 41W 120V) and replaced the old one. This fixed the issue with lack of suction. The machine now primes properly. The pump I bought had a slightly different connector where the T-joint threads in, so I had to remove the black O-ring gasket and replace it with Teflon tape wrapped around the threads to prevent it from leaking.
