I noticed the smell of gas while driving and when I looked under the hood I seen there was small amount of gas leaking from the hose (I looked it up and it's the fuel pressure regulator hose) where its connected to the Air Intake Resonator nipple. I don't know very much about cars even less about engines and the names to the parts I'm describing are from looking them up but I have yet to find out if there is supposed to be gas coming from this hose. So my question is of course, Is there supposed to be gas coming through this hose? 1999 Toyota 4Runner Limited, 6cil. 3.4L
Added a picture with an outline of where the gas is leaking from. Hope it helps, not really computer smart either.

NO. There should not be gas coming from that or any other hose under the hood. DO NOT drive the vehicle and have it towed to a shop.

Thank you Homer1967, I had already made it home but judging by your response I'm glad I made it home SAFE! I was online a couple more hours and what I have understood from the things I have read, it is the Fuel Pressure Regulator that has gone bad and thus letting gas leak through the hose. Again, not a for sure thing but it made sense to me after a couple people explained it to me. Thank u again for your help, I'm a little more wiser because of it.
