A member from DTR posted this on here awhile back, found it in my searches, when I was getting ready to pull my pump. The FSM also has a pic somewhat like this. This view is the backside of the VE, and shows where each injector line MUST go.

When reconnecting my lines back onto the pumps threaded ports, I could easily see how someone could accidentally connect the wrong line onto the wrong port, but I was prepared cause I labeled each of my lines prior to disconnecting them from the pump.

Excessive load from over sized tires/wheels will put extra strain on power train components. Will make a small problem show it's ugly head much faster and cause lots of problems.

That being said, sounds like a bad injector, get that taken care of quick, a burnt piston isn't cheap...

What you can see as an oring on top of the injection nozzle has nothing to do with your leak. That ring is actually a quad ring meaning it is square or has 4 corners to it, it is nothing more than a dust seal to keep debree from entering the space between the nut and nozzle body.

If you have fuel their it is coming from somewhere else. Possible the injection line itself and its seal with the nozzle or it is possible the nozzle has threaded apart but that's quite uncommon. The return line may also show up as a leak their but again not very commonly.

It bubbles from around the injector.

Standing behind the tailgate, facing towards the front of the truck, so the view looking at the back side of the pump. Whoever drew this up, was correct, as I double checked it when I one by one removed my lines at the pump, I labeled my lines and the ports.

Very good point. Pinion angle change can send bad harmonics up the mighty Cummings. Causing helter skelter!

For those who don't have a transparent tailgate/cab/firewall, the posted diagram will preserve its integrity if the back of the VE is viewed while looking at it standing by the drivers side front fender.

Agreed.

Amazing how butchered suspension components have an effect that is overlooked by most.

By the way, the correct term is "Cummins".

I had a similiar problem, got a new $800 custom driveshaft, with higher critical RPM, to correlate with higher pinion angle. which eliminated issue ...

Got them out. On the way to city diesel in Knoxville now. The number one was wet all the way up. The rest were dry as a bone. They came out very easy. Someone must have been in them before I bought the truck. NOW....IF a man wanted a little bigger injectors what would he buy. Right now I'm planing on just getting stock ones.
