Thank you so much for taking the time to post your findings. I also ordered PN 12614837 and got all the way to removing the original before realizing the discrepancy. I matched up a generic o-ring for replacement as closely as possible and it solved the leak until now. I have come back to this thread to see what part i ordered and discovered your replies. THANK you so much, as now i can install a correct replacement and be done with it.
Best regards and keep the rubber side down!!
