ANOTHER gas Leak????

So I'm leaving for work this morning and I smell fuel again. I throw down a towel and look under the jeep. I see nothing so, without getting my work clothes dirty, I stick my nose uder to I can sniff it out literally. Just in front of the driver rear tire, along the insider rail frame...I see fuel crawling along the rail. I'm going to get under there in my grubbies tonight but anyone know what I might encounter there? Rubber hose along there? filter? I just have not run the legnth of the fuel system and I'd like to get it handled tonight. Thanks

Sounds like the 90 degree hose to the filter went on you. It is easy to fix although it is a dealer only part.

That's pretty much where the filter is... could be rusted line, rotted rubber connections where the filter connects, or a rusted (or clogged) filter.

If you haven't done it in a while, might be a good place to start by replacing the filter anyway and the short pieces of rubber line that connect it

Good luck

Thanks...are all of those dealer only parts? I can run by an auto zone but not likely a dealer

The filter and rubber line(s) and new clamps should be available at just about any NAPA, auto zone, advance, pep boys, etc, etc.
on the rubber line, you're just getting a foot or two of hose (I forget, either 5/16 or 3/8), but you'll need FUEL INJECTION hose (not regular fuel line). regular fuel hose isn't made to handle the higher pressure... same with the hose clamps - use clamps rated for fuel injection.

Good luck

The 90 elbow is a dealer only part. It is such a sharp 90 that you have to use the dealer part. If I remember correctly the two end of the 90 elbow are different sizes too.

Trust me, you cannot get it at the auto parts. Maybe online at a Jeep site, for sure the dealer. Call your Jeep dealer tomorrow, they should have it in stock. Mine did. Change your fuel filter while you are there.

So I got up under there this weekend. Before I started her I looked up under there and those are the parts my guy replaced just a few months ago. Didn't realize that til I got up there. That is what I was referring to on the title to this thread. So two elbows, filter and the clamps are all sparkling new. I start here and climb back under there. Nothing, nada, zip. No leak. I wiggled it, I shook it, I pushed and pulled. No leak. The ONLY variable that I can think of between friday morning and saturday late afternoon when I looked, was outside temp. Is air temp a factor? Did not leak this morning either. But man it was coming out friday morning. Stumped

So BIG BUMP....same thing this morning. First time in a LONG time it has been "chilly" overnight. Jeep has been running leak free all summer. Start her (again in work clothes so I can't get down and dirty yet) and VIOLA, leaking from the same area. To refresh, my mechanic did replace all the filter and hoses...will check for hose clamps. But wondering if I have a combo of pressure related leak and it's made worse or only leaks with cooler temps. I'm hoping to get up under there in daylight with proper clothes...but would love to stop at auto parts on way home IF I need parts. Crap, leaking good this morning. at $4.35 a gallon.

Yeah I had that problem once just out of nowhere so I removed all the lines cleaned the steel line with a scrubbing pad put on new hose and clamps and no issues. Somehow the connection or the way the hose is seated it has a void and when cool it leaks. Just doesn't sound right but it happens.
