fuel leak from motor... need help!!

[lightn95]

so the other day i noticed a fairly large wet spot in my driveway where my truck had been ideling. i smelled it and its diesel fuel. i noticed it only leaks when its been sitting for a while (over night). tonight i started it in my garage and waited for it so start dripping. it started dripping after about 5 mins. its coming from a copper line on the passenger side of the motor just above the ground strap on the block. it looks like maybe its some type of drain/over flow, IDK.

what do i do to stop it from dripping

Looks like the fuel bowl drain line. It's the line that connects to the fuel filter housing to allow you to drain water and/or fuel from the fuel bowl (where your fuel filter resides). The gaskets and sleeves deteriorate over time and need to be replaced. I bought a fuel bowl rebuild kit on-line at dieselorings.com and just did it myself this weekend. Mine was hemorrhaging everywhere and now it's dry as a bone. Here's a link to the kit and they have great step by step directions with pictures. Cost me $25 instead of $450 for a new fuel bowl from the dealer.

There are also plenty of other posts here talking about the fuel bowl leaks

Just check it like 6 more times. Diesel and oil can follow different routes and make you think its one thing but its another.

its definately coming out of the copper tube, i watched it drip from it.

I just went through the same thing. Bob, at DieselORings.com suggested that I also replace the fuel line seal at the end of the passenger side cyl head. It's a bugger to get to but when I did mine it was definitely in need of replacement. He also suggested adding some rubber around the fuel line clamp that's located about midway on the head, right under the GPR. He said the fuel line rubs on that clamp and wouldn't ya know it, he was right.

More than likely water drain valve on ff housing. Orings are $20ish or $60 for a new drain at oriellys
