A pic would help, but the fuel pump is mounted just under the driver-side door on the frame...

You need to put the pic in your gallery or on a photo sharing site like WebShots or PhotoBucket...

That's really strange. Can you follow the lines from both ends to see where the lines terminate for sure? I'm thinking some kind of home-made CCV catch, but it's pretty small for that.

And so everyone doesn't have to go in his gallery, here's the pic:

That's a blurry picture, but i think it's some sort of a homemade ccv canister. Where does the other end of the hose go?

Pull the plug and see what comes out. CCV would be a good guess.

Thanks Izzy for posting that ok i just checked again and the line stops in front of the tank and is not attached to anything, just open So there is like a big mess back around my tank and on frame rails!! BTW this canister is leaking as you can see, I guess I will trace where it comes from

Follow the rubber line back into the engine compartment. CCV is also my guess.

It's a ccv line, it should go to the little housing on the rear of the drivers side valve cover.

Yeah, it looks like the PO did a CCV mod to your rig, but i'm not sure why that little bitty canister is even there, it has no media in it to catch the oil residue, unless that drain plug is pulled off the canister, it serves no purpose...IMHO, just take that thing off and let it vent to the atmosphere and get a vacuum plug from Advance Auto for the (not sure what it's called) place where the hose reconnects to the air intake tube...you can get a pack of various sized rubber vacuum hose plugs there for $2.89...i just bought a pack on Tuesday...


I will go get some pics for my gallery so ya'll can see WTF i'm talking about...lol
