LIMIT ( 1 ) per customer due to limited supply available from manufacturer.
** You can tell if you have Downflow or Upflow by the hole used for the Injector. They are marked DN ( downflow ) or UP ( upflow ). Whatever hole the Injector is installed into, would be the type of Valve Body you have.
Also, the Main piston is Amber ( only ) if Downflow, and Amber with Black, if Upflow.
If you are not sure, then send model number and photos before ordering this Valve Body.
