loose electrical connection...fuel pump relay
 

The fuel pump relay has been getting progressively looser in its connection in the power distribution box over the past several years. This is a 94 Ranger with 2.3l. The other relays are extremely tight fitting, but the fuel pump relay is getting loose to the point where the connection sometimes fails and I have to get out, open the hood and push the relay down and jiggle it a bit to restore the connection.
Can the connectors inside the power distribution box be made tighter somehow?
Thanks.
