Gates Plant master hose, 19b.
After reading other posts about issues with Gates Plant master hose, 19b. I checked my hoses. My hoses were replaced by Berndt in January 2016. We had previous issues with the wrong fittings being used creating air intrusion as I described in a separate post.
I have attached pictures of the hoses on the Genset. I am replacing all of them and inspecting the heater hose, also, which should be compatible.
I appreciate the earlier posts on this issue.
