Roger,
The list strips images.
The pump part number is normally on a aluminum tag that is attached
using two of the screws that hold the coil housing to the body of the pump.
You'll need to remove the end cap to have a look inside.
If it's a SU electronic pump, I'm not sure the polarity can be reversed
in the field. Is there a circuit board?
If there's a capacitor inside, then you should be okay. If there's a
diode, you need to reverse the leads on the diode. If there's a TVS,
should be okay as is. If there isn't anything but the points, you
should be okay too.
Cheers,
Bob Haskell
