Question Fuel Smell & Some Fuel Drippage

Today(4/4) I noticed on my way to work, I kept getting a slight whiff of fuel inside the cab. About 5min. before I got to work, I thought I couldn't smell it anymore. I even let the truck idle an extra couple of minutes to see if it would reproduce the smell, but didn't. On my way home from work, I was getting really good hints of fuel from when it got warm, all the way back to my driveway. I looked under the truck & couldn't find anything under where the engine is, but I did notice a constant drip around the inspection cover of the trans. For a second I was thinking the trans was leaking too, but when I got under the truck, it wasn't ATF, it's fuel. Then entire inspection cover has a glaze of fuel on it, there's a pretty good section of the trans lines that run by the starter that have fuel on them, & it looks like it's a narrow stream of fuel coming up from the engine.

When I got under the hood, there's wasn't anything jumping out at me; the fuel filter cover's tight, the fuel drain lever is in it's closed position, & there doesn't appear to be any other source of a fuel leak that I can see, anyway. There is a slight glaze of fuel on the cover, but it doesn't stink like fuel unless you practically have your nose on the "POWERSTROKE" cover above it. You can actually smell the fuel better UNDER the truck than under the hood. Has anyone else had this problem? Does anyone know where I can start looking? Thanks in advance.

put your boots on, and hike up top the motor. Look down inside the valley. If you see a puddle close/under the bowl/hpop, then your bowls' leaking..Riffraff Diesel: "Mechanics Parts Cabinet" Combo kit

If you see the puddle towards the back / turbo-pedestal area, then follow the pass side fuel line, leading toward the rear of the head. It is plumbed through what looks like a "P" clamp. There, the fuel line, overtime, rubs and creates a wear opening/crack, thus, your leak source..happy hunting.

Also, inspect the fuel line to where they connect at head/s. Sometimes, the parker sleeves, thats encased in the cap, wears out, causing a leak too.

Awesome! Much appreciated, man. It doesn't seem to be the fuel bowl, so I guess my next move is the pedistal area. That seems to be more the ticket. I'll check that out today after I get out of work. Thanks again!
