I need an internal vacuum check valve for a single port om617 vacuum pump. I figure someone may have a bad pump laying around that had a good internal check valve. There are 3 check valves inside the pump under the front cover. My pump has 1 failed valve. Thanks!

there is a repair kit for the 2 port vacuum pump that has a couple of those check valves.


pp sells the kit and its cheap

I didn't even think to check the older pump. Just found the kit and the check valves look identical. Thanks!!

I have the complete repair kit for the early style if you're interested.
