Where is it? The only thing I see remotely like the description of a PD is on the upper fule rail (the larger of the two rails). I believe the PD is supposed to be on the Primary rail, which is the closest to the motor...am I wrong?

 

that is correct. Your primary fuel rail SHOULD have one. Somebody may have beaten you to it and "fixed" it with a banjo bolt of sorts.

 

Primary Fuel Rail. Sits on the block unlike the secondary which sits on the lower intake manifold Looks like this. (yellow thing)
