Fuel Leak - Need help
Discovered a puddle under the truck last night as I was pulling out. When sitting there are no obvious leaks, but when idling there is a stream coming from the noted area in the picture. Any suggestion on where to start?

It looks like it is coming from a low point, so it must be hitting another surface and traveling down to where you show in the picture. Any chance of seeing where the leak leaves the fuel lines? It should be someplace above where you show in the picture.

Your fuel bowl has two hard lines, one for each cylinder head. The one that feeds the right side (passenger) runs under the GP and AIH relays and enters at the rear end (nearest the firewall). There is a clamp on the line around the turbo pedestal attachment. Remove that clamp and inspect the line for damage. If you find some damage, then repair or replace the line making sure to add some protection around the clamp so it doesn't damage your line again.

Sounds like a common problem with the 7.3 Take a look at the water seperator valve on the side of the fuel pump/filter. There are four #20 Torx screws that hold the body of the valve on. Remove them and pull the valve body off. There are two orings on the inside of the body that are probably shot! 1/2" OD 1/4" ID 1/8" thick. Look for replacement orings for fuel applications. While you have the valve body off try and clean the inside of the valve to get any grit out as well.
