Hello, I own a 2002 ford ranger 3.0 v6 4wd single cab. I am trying to find the EVAP service port location to do a DIY smoke test. I can not seem to locate the EVAP service port. A couple of videos said it would have a green cap. There is a line directly next to the battery on the driver side that has a cap but not green. I believe this to be the EVAP service port. If anyone could confirm this or help me locate the EVAP service port that would be great.
