Fuel lines burst today

Well, went out to warm up the heep for my wife this morning and it started dumping fuel in the driveway. Awesome. 19 below zero was too much for old rubber lines I guess. Looks like the fuel supply and the fuel return both cracked. Am I safe to assume the cold just messed up the rubber lines or is there something else I should check while I am at it?

I'd replace all the rubber fuel lines. If those two cracked, the others are probably not too far behind.

On a side note, ...dude... your wife is tough! Driving a YJ in -19 temps? D@mn.

Bundled well, I was comfortable on my way to work this morning (we're getting hit with snow as we speak, so the Jeep is pulling snow duty), but it was only down around 20. Somewhere around 10-15 is when I put on the insulated overalls... (Teach me your Jeep heating secrets)

Pull into a garage, fire up a heater (I keep meaning to get one) and replace the lines.

As for how to keep a Jeep warm, I am gathering that you guys have trouble staying warm in your Jeep? Regardless of the exterior temp, I can sweat in mine... Its hot a sh&^!! Thats with a hard top and full doors in the winter.

Heat in a Jeep? I would have to install a heater core first.

OP, bad time of year for this kind of work, but the rubber fuel lines all need to be replaced.

The wife is a tough one The heat works fairly well but it's still chilly in there. Driving a YJ in the mountains on the highway in the snow and ice every day of the winter is what rattles her. No fun driving that thing around in the winter. On the bright side though, it'll surely get you out of the ditch it'll surely put you in.

Well said. My DD is a Charger R/T. It is miserable on slick roads. I use the Jeep for fun top down driving in the summer, trails and crawling year round, and in bad weather (i.e. snow, ice, flooding).

I've got to get my hard top painted and installed... During my rebuild I put in a new heater core and installed a blazer fan motor. It definitely helped, but it's still chilly. All my gaskets are in good shape or new. The soft top isn't cutting it.

I agree. That's just too freaking cold to be driving mine. I remember driving from SW Missouri to Red Cloud Nebraska in the YJ back when it was my DD (we were pheasant hunting in North KS and Red Cloud was the closest town to get a room). It was about 10 degrees when I left home and -18 when I got there. I had a gas station coffee cup beside me that was half full of coffee frozen solid when I got to the motel (I'd been drinking it until it got cool).

The Charger gets nice and toasty ...which is good in snowy weather because I'd hate to freeze to death in the ditch! (Love that car though.) I'd love to have the engine from the Charger in my YJ, but a 302 will just have to do...

Glad the heat works in mine! I'd hate to freeze the coffee lol So...questions about removing the tank. Never done it before but it looks fairly straight forward and I'm ok with a wrench as long as it aint a diff...don't ask.

To remove it I just need to undo the filler hose and vent up in the tire well area. Then undo the three hoses underneath, supply, return, and vent. Put the jack under it and undo the seven bolts which I just loosened up to see if I'd have a prob with them being stuck. Lower it a little, undo the fuel gauge sender, and then lower it all the way right? Do I need to worry about the wiring for the fuel pump or is it long enough? I have a service manual but it doesn't mention the pump wiring. Gonna go look for a writeup after this.

I had mine down recently and I don't remember the wiring being a problem. There might even be a plug for it in the fender area.
