Thank you for the video. I'm going through refurbishing my '95 w140 PSE and replacing all the vacuum lines now. As I used up my last Johnson motor on my c140 last year, can you recommend a good alternative that's more readily available? Also, I think at least some of the pump vanes are worn sufficiently as to not generate enough pressure or vacuum which caused the existing motor to run too long, timing out some circuits and eventually burning up. Are there replacement vanes or even whole pump assemblies out there or do we just have to source used PSEs from breakers for parts?
