Fuel Leak

Howdy folks.

I am wandering the web trying to find some help for a problem with the truck.
'02 F350 7.3L Powerstroke.

* I am not a mechanic and don't pretend to be.
* I am not stupid. Although I will admit to considerable ignorance on matters automotive.
* I am not Rockafeller and if I can do this myself then I can use all the help I can get. If I can't then that's OK too.
* I am quite capable, can easily comprehend and have performed many repairs on many of the vehicles I have owned in my life. Usually it's a matter of having the info I need.
* I can build you a multi-million dollar mansion from the ground up.

I point this out only because of the responses (or lack there of) in reference to posts about this issue that I've made elsewhere. I don't look to come off wrong, just a guy who's looking for some help.

On to the problem. I've got a puddle of fuel in the valley on top of the engine. It is coming from somewhere on the turbo but I can't tell exactly where. It's a healthy drip. I am trying to find an exploded view of that area so I can wrap my head around what's what. What information I've been able to find suggests a pump. It's also been suggested that there is a "Separator" that could have cracked. Temps got down to single digits and I'm wondering if that may have had any bearing. The leak is definitely occurring on the back of the unit.

Any help would be greatly appreciated.

Thanks

Sounds like the fuel pump behind the fuel filter housing,I replaced mine last year,remember to replace the small hoses connected to it,not hard to replace just unbuckle the turbo for more room.

Generally the leak you describe comes from the drain line on your fuel filter housing, directly on the backside of the canister housing itself. There are two small o-rings in the drain valve that will corrode/dry out over time and leak by. It is very common on the 7.3L motors. Its an easy fix, all you need for tools is a small torques head socket to take out the 4 screws holding the drain valve in place and a pair of replacement o-rings you can get for less than $1. You can verify that this is the source of the leak, just start the truck and shine a flashlight behind your fuel filter and watch for a couple minutes. If the o-rings are shot you should notice a steady drip. Hope this helps, and you can build me a multi-million dollar mansion whenever you want...

Well, I'm into it. Had to take a break. Doing this in the cold w/ no garage is interesting to say the least. I've also learned that you need to be a 6'8" tall preying mantis with lights attached to your head to get in there. Anyway, I have a question about the drain positioning itself. I noticed there are two openings with each having a ball like valve and each valve with it's own opening. Should the two openings be aligned when it goes back in place and in what direction should the handle be facing for said alignment?

Hope that made sense.
