If you use another type of pump other than a centrifugal like the clear water pump, you definitely need to put in a sight tube because the level in the pump line is sometimes not accurate with other pumps. I had bad luck with cheap and small mag-drive stuff, haven't checked the link you posted though. I ve never seen one of the blue Clear Water pumps leak, though the black plastic housing over the wiring does fall apart if you get biodieel on it for a year and expose it to the elements and then drag it around all over the place for classes like I did. Get the SUrplus Center catalog as well if you're looking at suppliers of gear. mark
