Thanks...
Tightened the fuel leak... Man that made a mess... Now have a small coolant leak somewhere around the thermostat housing.
It appears to be leaking down the front of the motor and also running down the back of the motor. It started getting dark here so I called it a night.
Here is my updated balance rates. I replaced drivers side only 2,4,6,8...
Guess now I should start saving for the passengers side!

Okay guys I'm starting to get frustrated with this truck... Got the coolant leak fixed and everything was looking good. Took it about a mile or so to the gas station checked it again... Nothing leaking. Filled up the tank and now it's leaking fuel... Only seems to do it when the truck is running... I can't find anything on the top of the truck. All the return fuel lines look good... Underneath the truck it's leaking down the exhaust manifold cover on the drivers side, and falling onto the oil filter... Can't seem to trace it high enough on the bottom to find it. Any ideas?

Ck in the valley and around the driver side fuel rail. Some leaks won't show up at idle. If you have no way to ramp up the fuel pressure you can un plug the the cp3 pressure regulator, it will cause the cp3 to go to full pressure around 23,500+ psi or so... BE VERY CAREFULL WORKING AROUND THE FUEL SYSTEM MAXED OUT. Don't touch anything that is leaking, shut the truck off to continue repairs.

Thanks so much I found it. Ran the truck without the turbo boot on... It was a return line fiting... The truck is back on the road.
If anyone else is considering doing their injectors, go for it. I knew nothing about diesels before this. I could now do it in half the time. Thanks so much for the help guys!

Hey guys been driving the heck out of my Lb7... I love it! Only complaint is that at around 45-55 mph there is a noticeable vibration in the steering wheel. You can feel it all over just the truck bouncing up and down real fast. Not bad but it is noticeable. How does one go about finding the source?

One of the steer tires may have pitched a weight or broke a belt.
