I filled my jeep up for the first time after buying it a month ago. its a 90 yj with the 2.5. I was getting a bad fuel smell inside the cab. found where it was coming from. There are 2 rubber lines coming out of the passenger side of the fuel tank, into a tee, one line from the tee goes to a metal hard line sticking up into the passenger side quarter panel of the jeep. At the end of this hard line there is a broken off rubber hose. What is supposed to be at the end of this hose? thanks in advance.
