Dumping Fuel... Help!
Ok, so I just went out to take a ride to the store, and I pull out and see a puddle of fuel on the ground, and a trail to where I am. I take a drive around the block, and the trail follows me, and I lose about 1/8 of a tank or so in less than 5 mins. I turn off the truck and take a look at it, and it's a steady stream immediately after turning off the engine, then slows after time. From what I can tell, it's leaking somewhere high on the engine and dripping down to just behind the oil pan. It smells like just fuel to me, but who knows. Here's a picture to where I saw it dripping. It's a little bit dark now so I can't really take a good look at anything. Please, any ideas what this is, and how to fix it would be greatly appreciated. This is going to put a damper on me getting to and from work.

Either the dreaded fuel bowl fuel drain o-rings or a fuel line sleave to the heads let loose. Have somebody get in the truck and while your looking down in the motor compartment, above the fuel bowl, have the person turn the key to on, don't start, just turn the key to on and see where the fuel is spraying-pouring out. Be careful for spraying fuel, wear safety glasses.

From the sounds of it this is coming from the fuel connection on the passenger side head. There is a clamp that holds the fuel line that eventually rubs a hole in it. That is the best I can tell. With you dumping that much fuel that fast is the only thing I can think of. Either that or where the fuel supply lines connect to the fuel bowl.
Best thing to do is get a flashlight and pull the plastic "Powerstroke" vanity plate off and have a helper turn the key to on but do not start the engine. I have a feeling you will find your leak very quickly with that much fuel leaking.
That is my best guess at it. Hopefully someone will be along shortly with more to add.
You didnt happen to change fuel filters lately did you?
Also check the lid over your fuel filter make sure its snug and dry and go from there.
Mike has you set up right. He beat me too it. Too slow once again lol

What Mike said^^^. There is also a fuel line clamp that tends to rub. The fuel line goes from the fuel bowl to the passanger side rear head. There is also one on the drivers side front but that one doesn't seem to cause a problem for some reason. Check this thread: https://www.ford-trucks.com/forums/9...ml#post8996403

You may need to over haul your fuel bowl or replace the rubber gaskets in the fuel rails. Bob has a kit for the fuel bowl RR, ect.

I just replaced the fuel line because of the clamp-wear-through problem, except mine went on the highway after an hour of driving and turned my truck into a fuel-spraying-mist machine. my buddy in his 350 behind me got covered and i lost about 10 gallons or more in 5 minutes. got towed and replaced the fuel line with high temp rated rubber fuel line @ $5/foot. the replacement line is a dealer supplied part, and i didnt ahve the time or the desire to put the same faulty part back in. just be careful to not get dirt in the back of the head. let me know if that is your problem. it'll spray everywhere from behind the turbo area when the key is on.

I removed that passenger side fuel line from the p-clamp. Split a piece of rubber fuel line about two inches long and slipped it over that section of fuel line. Put the fuel line back in p-clamp and re-attached to it's mounting. Didn't need to disturb either connection. This was done as a preventative measure. Got this idea from SpringerPop.
E99s have a problem with the driver side fuel line rubbing on the rear of the IPR. I used a piece of split fuel line there as well and a small hose clamp to keep that section of fuel line from rubbing on the rear of IPR. 99.5 and up have a different shape fuel line that does not rub on the IPR, but I would check it anyway.

Had it been leaking I would have cut the hard line and used a piece of fuel injector hose to reconnect the two pieces and double hose clamped it on either side until I could have replaced the line.
