I replaced the monovalve with the kit. I priced it online and the best price was $30 and come change at www.importec.com
, but to get it in here by the next day, I would have had to pay bigger amounts on overnite shipping. I went to my local dealer and they had one for $44 and some change. My old monovalve diaphragm was completely busted. It is fixed. I did have a friend at a shop trouble shoot it and do the actual replacement. He charged me $40. That still was not bad considering it could have been something else that would have cost a lot more.
