Hello. I have a 2000 ford f350 7.3, auto. Srw. Noticed a small puddle under truck and smelled it, its diesel. Looked under truck and saw it coming from the sleeved lines under alternator area. My question is how to go about replacing these lines? Is there an o ring in the line that goes bad? Can I use any other diesel rated hoses instead of ordering the double sleeved lines? Also, what is the process of removal and installation, does alternator, serpentine belt, front cover, have to come off? Any help, tips would be much appreciated. Thank you.
