I am waiting for that part number to be sent to me right now from parker. As soon as I get the call back I will post it up.
Ok all, Here is the reply and part numbers provided by Parker for the units. They don't currently have a complete unit with housing and heater in stock. So you will have to purchase the same primer housing unit as posted above and then order the heater and install it yourself. There are two different heaters, 12v and 24v. I will post both as I am not sure which one we use on our trucks, Would assume 24v. Can someone chime in on this? The heater unit comes with the heater and new bowl. You just remove the one you have and replace with the other. Then you will have a spare bowl.
Fuel water separator is PN 445R10- Filter housing and primer bulb unit
Heater unit PN 12v heater is RK22616-01
Heater unit PN 24v heater is RK22616-02
Hope this helps.
