Sorry if this is not the right forum, but I have just purchased a 2006 Mazda B2300 and there was a known vacuum leak pointed out by the original owner. It has been wrapped in duct tape, but was still leaking. I was looking at it the other day because it seems to be whats causing the lean bank code I am getting and now it is leaking a lot. Seems to make the car surge and stutter now while accelerating. I want to replace this hose, but am trying to figure out what hose it is. I have attached some pictures, you can see the tape and I have circled it. This is the back of the intake manifold.
