I have a leak on one of the lines going from the front of rhe truck to the rear unit it runs through the nottom of truck between the frame and catalytic converter i have almost no room with my big hands any ideas in how to remove it to replace it (diy project) I previously had put a aluminium putty sort of like jb, it held for about a year now im thinking of replacing it but need help with diagrams or if is one whole line or is it sections hopefully.... Any help thanks.....

 

Wow, that's really specialized.

Possible if someone else has one, crawls under and looks and comes up with something, or has the Ford shop manual for that model & year, if it says anything about how to get at it.

Otherwise, I wonder if the cheapest online subscription to AllData.com for your year and model would have anything on it, other than a exploded diagram with the base part numbers on it. That would show if it's more than one piece. Might/might not have a replacement procedure, as far as access. I sure don't know.
