If it's one or more of the push-on connectors, usually a gentle squeeze with pliers, as mentioned above, will cure it. Best to do it with the power to the pump off. Place the pliers so that you're squeezing wide-side to wide-side on the white plastic of the connector. The idea is to deform the metal inside the plastic just a bit to tighten the push-on connector.

it is possible you have loose or corroded connections... pull out one line feed to pump at a time and see is you can squeexe the female connector so it is tighter for the spade slide in connection. dont squeeze it too much . trial and error just a little bit. see if that solves your problem .
sounds like you have loose connections.
