Fuel Leak and Rough Idle

I just got mu truck and today I drove it up to work which is only three miles. When I got out I noticed a small puddle under the truck. It was Diesel dripping down from back side of engine. Opened hood and could see fuel down in the vally but could not pinpoint a leak. Any infor on this problem or any help at all. Also it idles rough it has been doing this for a while now. And thats it. Starts great and runs excellent down the road just idles rough. All info greatly appreciated. And yes I am new to the Powerstroke world.

Well I guess I will just order the O-ring kit for the fuel canister and go buy me a couple of hoses and clamps to fix whatever is leaking.

As to the rough/lopey idle any input?

the leak could cause it or the FPR screens clogged also when the fuel pump gets old it spikes fuel PSI and the engine goes with it

Well I pulled the canister out and replaced the bottom hose coming from the fuel pump that was leaking. Went ahead and replaced all the hoses since I had it out. Now there is a leak coming from the sensor on the lower back of the canister. I guess I will just order the Oring kit and a new sensor and hopefully get this leak problem fixed for a little while.

On a side note after replacing those hoses it seems to be ideling a little smoother.
