Well it was time to replace my rear heater hose at the firewall that feeds the valve. I first did this back in 08 and felt it was time to replace. Went to the local napa and went on search with the parts guy and came up with this. No idea what it is for and I’d did not have to modify at all. Got rid of the old tube and two hose style. Makes little cleaner set up and one less connection. Hose was 13 bucks.
