I have no idea if it’s the hand pump that's the issue or what.

Let me understand a little more. Does you electric pump run continuously? Does it cycle, or just runs occasionally to maintain the pressure? You could try putting a few drops of oil into the hand pump inlet, that might make it work better.

There’s nothing wrong with my electric pumps. I thought there might be something wrong with my manual pump, but then I realized that the tubing was the problem. I switched out one of the pieces of tubing and now everything is fine.
