I would check to be on the safe side the fuel filter is going in the right direction. The arrow is pointing towards the engine away from the fuel tank, Then you need to make sure the fuel pump wiring connections are good contact and did not come loose when driving.

i had the same issue after having replaced the egr sensor and the O2 sensors turns out the fuel pump was bad.

Before spending several hundres on a fuel pump, I recommend doing a fuel pressure test. You can get a test gauge pretty cheap at a parts store. If the pump is junk, you raise the truck, lower the fuel tank, unplug the electronics from the pump at the top of the tank, then with a hammer and flat head scrwedrive, gently tap the lock ring in a counter clockwise direction until it pops off. Pull the pump assembly out and install the new one. Reverse directions to install.

The only way I know of to get the diagram you are looking for is to acquire a "build book". Even dealer service manuals don't have this diagram. I got one from faxonautoliterature for $49 plus shipping. A better bet would be to find a spot on either end of the leak where you can work on it easily and work from there. Hope this helps.
