Hi sidney123,
Air is being sucked into the system and there are 2 possibilities.
1. The delivery hose from reservoir is leaking and air can get into system.
2. The pump is faulty and leaking which would draw air into the system as it operates. You need to service the pump and replace the seals, O rings to rectify. If there are damages to the shaft internally, the pump needs to be replaced.
