NumberDummy: Thanks for the tip on the light. Although I think that I do have a pressure problem. My new gauge is recording low pressure. If I keep getting warnings even after I have re-established pressure then maybe it is time for a a new switch, etc. But I would have to agree with some of the other folks here that my problems probably are coming from either a blocked pick-up, bad pump, loose connection with the pick-up, or sludge. I will find out shortly and report back. Thanks.
