Gas smell,any suggestions?

Any help here would be appreciated. I have a 96 with a 4.0. A couple of days ago I started to get the smell of gas inside. This occurs only inside while driving and doesn't really dissipate when the windows are opened; also, my milage has started to drop. The gas cap is intact and I cannot find a leak. Thanks for the help

You might want to check your injectors. The O-rings could be leaking, or worse, the injectors themselves could be leaking. I had the same problem myself. I thought O-rings were going out so I changed all of them and it still leaked. I found the 3 injectors that were leaking and replaced them. A week later, the other 3 leaked so I replaced them. Aftermarket injectors can run kinda high. I paid close to $300 for them. I would check out the ford injectors. they are the same and cost about $125 for a set of 6. Dont forget the check the fuel lines where they connect to the fuel rail. The O-rings in them can go bad. Good luck.

Suggest you not drive the vehicle until the source of the smell has been identified and corrected. If it is a leaky injector (or more than one), it can result in a fire. I watched a nice red XJ burn up in front of a former GF's house due to that. It also happened to one of our members -- who knew it was leaking and drove to the dealership to buy new o-rings. It burned up outside the dealership while he was standing at the parts counter.

I would also check your fuel filter. I replacved mine over the summer with a brand spankin new one from jeep, and it started to leak from around the seam. I checked everything thinking that it could never be the new filter. I was wrong. EL cheapo one from auto zone is holding up just fine now.

I have had this problem for about 6 months. I have done checks on the lines from tank to rail and back, checked injectors, O-rings, clips, name it and it has been checked. No leak found, and it only does it on long runs. I know it is leaking because of the fuel smell, but also if I shut it off, and restart it, it fires up, let set for a while and it cranks alot before it fires up. I have no clue where the leak is, but it is releasing the pressure on the fuel rail. Milage is irratic. Drove 200+ miles to go to a lake, drove around for 2 days and used a quarter tank, toke a trip ~275-300 miles and used a full tank, and it was all high way driving, the lake trip was through the mountains, up and down.

Your tank could have a pin hole in it. I had a gas smell last year and it was the lines leading to the fuel filter. Replaced them all and put a new fuel filter in. Everything was fine for a few months, and the I started to smell the leak again. It turned out that the tank had rusted along the bottom where it came in contact ever so slightly with the tank skid. just a pin hole, but when the pressure really built up, it would leak. So I replaced the tank and fuel pump.
Good luck and I agree with Eagle, find out what the problem is before driving it anywhere.

And the winner is?

Thanks guys everyone was about the injector. Eagle, I actually haven't been running since the day I started to smell the gas, fire insurance will cover the xj, but I think I'll opt out of being included in the festivities. I ran home and checked it, god I love living close to work, and noticed the #2 injector had some moisture when the motor was turned over. Time to pick up some o-rings....

Before removing the injectors, tank or any other parts I would recommend checking the high pressure fuel line where it curves and plugs into the injector rail----check the plastic-formed section that's molded to the stainless tubes.

You need to look real close because these develop pinholes and will squirt a fine mist of gas on the intake manifold and will eventually drip and run down the tube close to the exhaust manifold.

Mine did very same thing ...

Thank you all for the help! Cheers.
