I have a 94 F-350 with the 7.3 IDI. It has about 265,000 miles on it. It doesn't get ran much, only to haul trash/wood/trailer and such. I noticed the other day that it had some fuel sitting on top of the heads as if the injectors or something in that area was leaking fuel. I don't have a garage and the weather is crappy today, so I haven't had a chance to really look into it yet. Looking around on this site, it seems that most people with injectors leaking made a mistake when reinstalling them, mine haven't been off since I've had the truck, and thats been about 3 years. I'm pretty handy, but I haven't worked on diesels before, much less this one. Anybody have any suggestions on what to check first on this engine? Thanks for any advice.

I would look @ the fuel return lines. the lines themselves could be shot or the o-rings under the return line caps could be shot.

Sounds like your return lines need to be replaced. That would be my first check.
A repair kit is about $30, and if you don't have a turbo, (maybe even if you do), you should be able to replaced them in about an hour.

yep return lines are easy.

If thats it, will I need to replace lines and o-rings or just the rings? What are they called and where can I get them? Searching napa and advances website doesn't bring up anything for fuel return line.
Thanks for the quick replies.

i bought my o-rings from the ford dealer.
1 package containing 16 o-rings = $16.48+tax
good deal as far as i am concerned.
If you go to www.fordparts.com you should be able to find the return lines & $.
