Raw fuel smell
I keep catching whiffs of raw fuel when the truck is running. Today was the first day I noticed it. Looked around and didn't see any apparent leaks, made sure my water separator was closed, don't see it under the truck anywhere. Is there any suspect spots I should check? I know it's a diesel and I'm going to pry smell it every now and then but I could definatly smell it in the engine bay when I was poking around. And my vents when I had them on. Just a whiff every now and again. What do you all think? Sorry if it sounds like a dumb question. Still learning here. truck doesn't run any different maybe I'm just being over cautions. But the only place I want my fuel going is the combustion chamber!

Thats what I thought. Also known as IPR right? Come to think of it, it did look a little damp around right there, maybe tweak it a bit? I know its fragile, I do have a service record of it being out to be cleaned about 50K ago.
It was warmed up when I smelled it.

No, the ipr (injection pressure regulator) is on the backside of the high pressure oil pump (hpop). I have read on here though of an ipr causing this issue before. I have no first hand experience with it, the person who posted it hasn't been on here for while (Action...). He is a well respected and smart member though.

Thanks for clearing that up, I didn't realize they were 2 different things. Might try tweaking that tomorrow, It can't be leaking very much, all the other lines look good (from what I can see) never saw a drop on the ground. I'll keep checking around.

Yeah I haven't smelled it again since I got home. Put the AC in max and it went away. Took the boat out for a while and then came home, still haven't smelled anything.
I spose its like anything with 359K, there might be a bad hose or 2 haha. I'll get a flashlight down in there and see if I can see better.

What is this thing and how do I make it stop leaking?
Well I drove it again today, its definatly after you get it good and hot.
I saw this thing was wet and wet underneath, and it smells like fuel. What is it? I tweaked it about a half turn but I didn't want to over tighten it. It also may have had some fuel inside the plug which if thats the case then this thing might need to be replaced. but I dont know what it is. It goes into the side of the fuel bowl Here is is pic:
