Bill,

I have no idea why it crapped out. It was working fine the day before. I ha=
ve finger strainers in the tanks and an inline filter (not sure of the mesh=
 size offhand) before the pumps. This filter use to catch a lot of building=
 debris and dust but has been clean of late. I have a big ol canister filte=
r after the pumps and before the injectors.=20

I have power at the pump but even though the new filter came in today, I wi=
ll likely swap the auxiliary pumps power to the primary just to verify the =
power test.=20

I have heard of problems of running the pumps dry and avoid it, however, I =
have done do a couple of time unwittingly for a number of seconds. Perhaps =
the damage was done and it took a while to manifest itself.=20
