ok I have a fuel leak at idle i can actually see fuel driping down from the engine bay any suggestions im thinking the fpr but i just had it replaced with my new motor they also cleaned my injectors and everything???

 

It is most likey the PD (pulsation damper) or one of the hoses. The UIM will have to come off so you can see exactly where it is leaking. DO NOT DRIVE THE CAR with a fuel leak.

 

I just picked up a 94 FD and after driving it home 1100 miles, it developed a fuel smell under the UIM the next day.

Its probably my FPD and I am in the process of removing everything to get to it.

Or it could be like me. When we finished putting everything back in my car a friend smelt fuel. So we checked and under the UIM there is a small fuel line well the clamps weren't tying it down and sealing properly so fuel was leaking. Clamp was put at a better position and it stopped.
