Im pretty sure it's a line. Just don't feel like crawling around it right now. Just did the rear brakes and lines on my CJ7 and as soon as I got it firmed up, popped the front line. Anyways we are looking at 6"-10" of snow tonight. [emoji944]
Update, 12" of snow fell.
Also think that my thermostat is not working. Bus doesn't warm up at all. Anyone else done there therm? Looks like a nightmare getting in there.
Theres 3 small bolts holding on the thermo cover. Be careful not to break them! I got away with just two bolts after I broke one. Its right up front-easy to get at.
These things take forever to warm up at idle-you probably wouldn't get any heat blowing for 15 minutes or so.

Not sure what the earlier 7.3L engine room looks like, but on the later ones (1999 - 2003) you have to remove the air filter housing to get at the engine.
