Fuel? leak

[NWStroker01]

When I came home from the golf course today I noticed a wet spot on my driveway. I stuck my fingers in it and smelled it, not oil, but doesn't smell like diesel either ( might be ulsd?). Anyway leak would be coming from right (passenger) side of motor. Is the fuel filter located on that side? or maybe the fuel water drain? I'm new to working on my own rig, so any help is really appreciated. Thanks, Kevin.

prolly the water drain off lever not closed all the way. look on top of the motor on the fuel filter canister and on the passenger side back of it there should be a yelow lever, just push it to the closed position and see if that fixes it

Check also to see if the valve is just plain leaking along with if it is open. They are bad to go out.

Thanks for the info guys. I looked on the top of the motor (valley) and found a canister about 4" in diameter toward the front of the valley. I assume this is the fuel filter canister. Like you said dirty, there was a yellow lever-looking tab on the passenger side rear of the canister. I tried to gently move the lever-no go. It doesn't move. I didn't find any leaking around the lever either. I apologize for my mechanical ineptitude--but its improving.

For the most part it is dry. A little oil, about the size of a half dollar. I've had to have the hpop replaced in the past and they never did totally clean out the valley, so I think it is old stuff. Also no other evidence of leakage in the area, just diesel on the ground on passenger side.

if the valley id fairly dry and you are sure its fuel, check the fuel return line on the back side of the right head ,there is o-ring there that could leak as well and run down back side of engine

Check for the end of a black drain hose that hangs close to the front axle on the passenger side. That's the drain for the fuel/water separator (the yellow lever). Mine leaked most when the engine started up, then stopped. After a week or two, it leaked all the time.

Replacing the O-rings fixed the problem. Cost was an hour of time and $6 for the rings.

Thanks Bama, I found some viton o-rings on ebay for $4.50. Just waiting for delivery.

What color was the liquid you found?? How far out from the motor on the passenger side?? Had you been driving the truck?? Could have been condensation dripping, like when you run the A/C. I know mine has a nice puddle under it passenger side toward the back of the motor, but closer to the fender. Just my two cents. Hopefully you have found your problem.
