How do I remove the old part? I am afraid to force it off.
Answer Andrew, You will need to be careful, The retaining clip is no longer available. The best bet is to "unscrew" the upper wash arm snap outlet
912680 from the manifold pipe and use a pair of needle nose pliers to compress the snap retainer fingers, and press the snap out of the outlet, Reverse the procedure to install the new arm. Just be careful with the manifild pipe, you don't want to accidentally press it up and out of the top tub opening. Good Luck and Thanks
