Received on time and installed.  The problem is the return line from the water filter is 5/16 and since the fittings on the old one were tube compression I needed a 5/16 compression fitting to connect to the solenoids.  I hada to go and buy a 5/16 to 1/4" adaptor and 1/4 compression fitting to complete the repair.  The product listing said this was OEM and apparently it wasn't.
