2006 6.0L PSD Fuel Leak

My 2006 F350 6.0L PS is leaking diesel fuel and its gradually getting worse, I can smell it in the cab and I leave a puddle of gold everywhere I go. I tried to located the source and figured that the highest point would be a good place to start, so with that said. There is a little cylinder shaped sensor (???) next to the secondary filter housing, but its closer to the front of the intake manifold and has a plug with 5 wires fed to it, the colors are (left to right) Red, Blk/Wht, Grn/Org, Gry/Red, Wht/Red. I don't know what this sensor is but its very wet around it and the leak runs down the intake manifold until it drips down the back passenger side of the engine. I am assuming this is a bad O-ring leaking by, but I am trying to avoid the dealership if at all possible. Any experience with this guys? Your advice will be greatly appreciated.

Re: 2006 6.0L PSD Fuel Leak

Dude that's the EGR valve you are pointing at, and if you are seeing puddles of gold that is coolant you are leaking. Looks like you are going under the knife for some work, hopefully covered by warranty.



You see, in this world there's two kinds of people my friend....those with loaded guns, and those who dig.

You dig.

Re: 2006 6.0L PSD Fuel Leak

check all the fittings around the small fuel filter housing.

Yea hopefully its something as easy as the o-ring missing or fouled up on the cover. Least its a good place to start looking and shouldn't be too hard.

Wondering about the EGR valve, it does appear to be missing one of the bolts holding it down. It fits in pretty tight so I don't see it cause much of a leak but ya never know, would most likely be coolant and not fuel though.

Re: 2006 6.0L PSD Fuel Leak

its not missing at bolt. the empty hole is part of the intake elbow that is
pictured above the egr valve. looks like it could be a fuel line o-ring or even a cracked fuel filer lid. i have seen many cracked from a over torqued filter cap

Re: 2006 6.0L PSD Fuel Leak

Ok I will check all the lines and fittings to the fuel filter housing to make sure that maybe I am not just seeing some fuel being sprayed by a pin hole leak or something. I guess you never can be to sure. I will get back to ya'll with my findings soon.

Re: 2006 6.0L PSD Fuel Leak

Ok guys I cleaned of the manifold with some simple green. So, I could start over new and I drove around a lil and now I am seeing some seapage from intake elbow where it bolts to the intake manifold. And the fittings on the secondary fuel filter housing seem to be wet and smell of diesel. No current signs of leaking from the cap on the filter housing, yet. I will tighten these fittings on the housing clean and check later. I attached to photos from 2 different angles the one on the left is taken from the front of the engine the one on the right from the passenger side.

Re: 2006 6.0L PSD Fuel Leak

Pull the intake elbow off or the EGR valve and inspect the inside. I'd hate for you hydrolock the motor with coolant.
