Two Story House- No Oil

you're definitely losing prime. It might help to put the check valve after the filter so it doesn't get sludge in it.

If this is an underground tank, consider properly abandoning it and installing inside tanks.

    I changed the oil filter yesterday and the oil in the lines keep running dry. I primed the pump and got oil again and lost it this morning.

    What could be going wrong? There is a check valve in the supply line followed by a shut off valve then the oil filter and the pump. Then it goes back to the tank. Could the check valve be malfunctioning?

    Since the...

    problem began after you changed the filter, I would check the gasket on the filter cartridge or housing... It need not be leaking oil to draw in air.

    Thanks to you both. My initial thought was that air could be getting in so I took a suction reading and it was fine. Also don't you think I would get cruddy combustion if it was sucking air in? And that is a question not a comment.

    I just replaced the check valve and put it downstream of the filter. So far so good. I guess we'll see tomorrow.
