I have a 1998 ZJ (5.2) and I am having issues identifying one of the lines running under the truck. I also have a 1996 ZJ (4.0) that has this same line.
The line in this picture with the thick section just above the electrical connection runs into the fuel tank and is a plastic tube and runs down the length of the drivers side unibody rail.
Under the driver's floorboard area it transitions in to a hard line and runs up into the engine bay and comes out along the driver's front fender under the brake master cylinder. In this photo, the hard and soft lines are not connected.
Just after it reaches the fender area it transitions back to a plastic line. This photo is more up under the master cylinder where the firewall meets the fender. It is still hard line at this point.
It terminates in a "hole" under the driver's side headlight. In this photo I've pulled it out of the hole in order to see the end of the line run.
Where the plastic line and the hard line come together under the driver's footwell, the soft line smells a little of gas. Where the line terminates under the driver's headlight it doesn't smell like anything. Where the hard and soft lines come together there is some unidentified fluid on the unibody rail. I'm fairly certain that the fluid is brake fluid, and I'm also certain that it is unrelated to this line as the Jeep had a broken hard brake line that had sent brake fluid all over the place.
Anyone know what this line is for? I'm assuming its a vent line of some sort.
