Fuel leak

[surfingsnow510]

I was driving this morning to work and on the way it was a little bit chilly in my truck, so I had the heat on ( its florida so it doesn't usually get used) and I started smelling something, I thought it was fuel, but I wasn't too sure so I turned the heat off cause I was warm enough, hen I got to work I smelled fuel too so I look under my truck and it has a pretty steady drip about every second, so I crawled up under there and looked and it looked like it was coming from the back of the engine/ front of the tranny, but now it's covered the right leafs, sway bar, pumpkin, it looks like it's been slowly leaking for a while, but the weird this is its ran totally normal and i cant ever smell it with my windows down but i can with the heat on, I'm just wondering what this could be?

Most likely is going to either be secondary fuel filter cap oring or fuel pressure regulator housing oring on secondary filter housing

that's about 20 mins worth of it leaking, it seems to be slowing down a lot, just pretty much dripping off of the stuff that is soaked

There is one or two fuel line connections at the left front corner of your engine. Check that out. That failed connection has been suspected of spraying fuel on the hot manifold and causing fires.

Left as driver or passenger? The dripping is coming from the passenger side, and yea, if this is that it is really close to the manifolds

There is are 2 quick connect on driver side under exhaust manifold,4 connections at fuel filter housing on engine and then 1 connection on the front of each cylinder head

I'll check them today, it's weird, it's only the days that its really cold that it does it. My truck hasn't done a single time since I posted this until this morning, it's been real cold this week ( like in the 30s or 40s) so I'm not sure if that has anything to do with it

Hmm that is odd!! Possible that the cold weather is making orings harder causing a leak but who knows!! Just another thing affected by temp in a 6.0! There is also a plug in the back of both heads that fuel could leak thru. It will either be silver or gold and has a 6mm allen head hole in it. Good luck!
