Nothing to it. Take the line from the VCV on the side of the IP that goes to the BFS and route it directly the transmission modulator. Look for the line attached to the top off-center of the BFS. Both the line from the VCV and the line to the modulator have a cylindrical green damper. You only need one damper but I believe it's directional.

#4 hard line is leaking at the injector end. I came home on a trip and detected excessive diesel smell. I opened the engine compartment and found fuel leak on top of the #4 injector. I put wrench on it, but it was tight. I took the line off and cleaned the end with scott-brite, that did not help either. I can see diesel shooting out at the top of nut and not at the return lines.
Questions:
1. Is this a common problem with the hard line leaking? I noticed my #6 is also new (from the last owner)

It happens. When it leaks at that fitting, most likely the fitting was overtightened deforming the ball and socket seal. Not having proper alignment of the line and injector when tightening the nut can cause the line to rub against the nut eventually causing a leak. The line is already weak where it's swedged into a ball.

I suppose but I've never heard of it. It's more common for an injector to leak between casing halves when corrosion forms between halves. It's strange how a leak can develop after 200-300K miles of not leaking. Seems a more common problem when running WVO without proper 'dewatering.'

Define loud. A lazy lifter or tired belt damper will cause a clacking sound at idle. With the engine running, put pressure on the upper attachment of the belt damper. Push down on the attachment or pry the attachment away from the head. If that quiets the clacking, you need a new damper. MB brand seem to last twice as long as other brands without costing twice as much.
If you see an oil leak by the chain tensioner and #1 exhaust runner and/or a grimy alternator, there's a good chance the head gasket is failing. Debris from the disintegrating head gasket gets into the oil passages feeding the hydraulic lash adjusters. If there's no other indication of a failing head gasket, running synthetic oil for 10-15k miles often quiets the lash adjusters.
