Jeep spraying gas at intersection

Rough day. Sitting a traffic light w/ a 9 year old in the back. My doors are off and I could barely smell some gas fumes but didn't think much of it. Then a truck full of landscapers roll down their window to tell me, "Hey, is that water spraying out of the back?" Nope, not water. From my driver's side rear wheel well is gasoline spraying everywhere.

Long story short, I clearly have a problem with one of the pressurized hoses in my fuel system. From what I have read, it sounds like it could be the return line. The NAPA guy basically told me that NAPA doesn't carry anything that can help me and the dealership might not either. Does anyone have any ideas as to what it could be (more specifically) and where I can get the hoses?

They must have been looking for premade hoses like some vehicles have. I just bought bulk high pressure fuel line at Advance Auto. I think it was 3/8" and I got about 6 feet and had some left over. The lines run through a grommet in a crossmember ahead of the tank and I couldn't get the old lines out so I rerouted the new ones around the crossmember and made sure they were safely routed. If it is "spraying" it is probably the pressure line. I would replace both.

Are both hoses the same diameter? I was under the impression that one was 3/8 and another was 5/8.

It's been a while and I am getting forgetful, almost certain the pressure line is 3/8" but the return could be 5/16" but not 5/8". The front end of them connect ahead of the tank so you can check by crawling under and looking before dropping the tank. Maybe someone else knows the size offhand.

Yes, you can buy them in bulk from just about any autoparts store. I replaced all of my rubber hoses 2 years ago, and I think I used a whopping 8 feet total between the 2, with some left over. Just make sure it is FOR FUEL INJECTION ONLY. Those lines are under a lot of pressure, and the fuel injected lines are stronger than the standard fuel lines that are used to feed the carbs.

1991 YJ, rebuilt 4.0L in spring 2009 at 234,000 miles, no lift yet, slightly offset wheels, 235/75/15 tires for now, rag top, sold the hard top. Over 35,000 miles on the rebuild and counting.

My money is on the fuel filter. Those hoses that connect it to the hard lines. IIRC I got some standard 5/16" fuel hose and replaced the old cracked ones. There is one that is bent at 90 degrees but I was still able to use just standard fuel line.

Your napa guys sucks man. I walked into napa and had a piece of fuel hose and said you have anything I can replace this with, he pointed to a spool on the wall and said how much you need?

with this ^^^. I've had it happen on my '94. It sprayed like a garden hose with a hole in it. I've used the same fix Louie did, but made sure to clamp it down well. the hard line is a slightly different diameter than the tank side of the filter connection. Leave enough slack that the hose doesn't kink at the 90 deg. turn. I put an extra hose clamp right in the bend to help keep the hose round and help keep it from kinking. (I hope)

Mine was doing the same thing and somehow one of the clamps had come loose and walked-off the hose and another clamp was loose. 30 seconds with a flathead screwdriver and she was good to go.

There may be a few reasons for the gas leak.

1) The rubber gasket for your sending unit has disintegrated. Possibly dealer only part, and there was a recall on it, if it is still active I do not know.

2) The fuel line to the fuel pump has cracked. There are two. One of the lines is a dealer only part because one end is larger than the other end. You can force a new hose on but you will eventually have another problem. Buy the right hose.

3) There is a 90 degree piece of hose just before your fuel filter that has cracked. This is also a dealer only part although I have heard of some placing a tube into a piece of hose to make the 90 degree piece. My advise is, Buy the right hose.

I know about all three because they happened to me. If I was you I would replace all three the right way so that it does not become another problem later. Ask me how I know this? Now everything is new.

Common for the hard lines to seperate from the soft lines near the gas tank. Add a screw tight clamp on it if needed.

Use the right clamps to make sure that they are designed for the FI line. Yes there is a difference the edge is rounded just a bit to keep from tearing the hose.

A 89 yj with a 4.0 aw4 sye out of an 92xj. Now the hard part is done time to get it up in the air just a bit. Working on 8.8 with 3.73 and lsd for the rear. and new D30 hp with 3.73 .
For those who have not figured this out I'm old school but can handle the new too.
