Hello,
Not that we won't call you but that isn't' the norm. . .. . .so lets try this one more time to see if this works for you.
Also, just a note. . .. . ..just so happens you got me again. That was by chance. We literally get thousands of posts and many of us work them. So to ensure we help you, please make sure you include all the info on your vehicle each time, otherwise it will waste your precious time on getting your vehicle back up and running and we don't want to give you the wrong data. I was able to look back and find your post but you never did in that one answer the specifics on your truck. Then I used a K2500 P/U, 4WD, V8-5.7L, VIN R. If this is not your vehicle please make sure you provide all that and the 8th digit of your VIN.
Okay, if I understand your question, you have two hose connectors on the purge vac diagnostic switch.
I have attached the pic again for the vehicle listed above. If you follow that, start with #2 the EVAP canister purge solenoid valve. A hose comes out of that and goes into one side of #1, the EVAP purge vacuum switch. From the other side of that switch, a long hose goes to the driver's side, most outside connection to #6, the EVAP canister Vent. From the inside of that vent, that hose goes to your fuel tank.
You sound frustrated on your email and I would be too. Vehicles not running right, needs inspection. . .. . .. . ..we understand. We will do our best to help you here. Try this first. If this doesn't work for you then get back with us and we will look at calling. But please ensure you have provided all of the detailed vehicle info first so that can be looked up and ready.
Hang in there Joe B. . .. . ...we'll get it.
