Are Little Giant and March heads interchangeable?

[sandyabernethy]

I've got an old Little Giant pump on a Sabco Brew Magic.
Having problems with air in the line and a very small leak at the pump head. (I suspect the O-ring.)
Wanted to replace the impeller with the March 815 impeller and a new O-ring and silicone washer IF they fit the Little Giant pump.
Anybody know about the interchangeability of these things?

Maybe the March Pumps people will chime in, or read through the semi long thread.......

totally different impellers so it's not going to work. The orings are only a few bucks, but my guess it isn't the oring leaking causing the air in the lines. You would see drips from the head before you would have air in the lines.
