ok, i finally found my fuel leak on my 2000 5.9, hopefully i can describe. its on a little steel line on the return side. from the vp44 the return line runs behind the fuel filter housing and into a "T". from that, one side (top) goes to the back of the head (i think) and the other goes down to a plastice connector to the return line that goes back to the tank. i need the little steel line on the bottom of the tee. its about 2 - 3 inches long and has a 45 degree bend in it. can anyone help. sure wish i had a diagram.
