I have a question for you all. I did a search but came up with no answers. I went to leave work yesterday and I noticed a few "drips" coming from UNDER the Powerstroke near the inspection cover (where the engine and trans come together). The longer the truck idled (it was cold here); it became a steady drip or drips (almost a stream)! It was not oil or trans fluid, it IS diesel fuel. The whole intake was a pool of fuel! I have not yet changed the fuel filter, could it be clogged? Or is it more likely a bad fuel pump or line?

 

I just checked, and it seems that the top of the fuel filter is spewing diesel fuel everywhere! Must be a clogged filter?

 

I would have thought you would have got a warning light or even had the truck stall before pressure from a blocked filter would blow the top seal. Might as well get a new filter and make sure and follow the instructions about locking the tab in the cap and bevel on the seal up. Before you pull the top off open the sediment drain valve and leave it open. if you don't get any flow onto the ground, sediment bowl is really clogged. Start the truck and open it so pressure will flush it. Then stop the truck leaving the valve open and change the filter. I cant't stress enough about being careful with the bevel seal install, easy to pinch. The fuel pump is also located up top, looks like a standard (probably is) mechanical driven gas engine fuel pump, maybe thats the culprit, but I'd start with the filter.

 

Make sure you get the cap on tight, too. I changed my filter in the road when my truck died (crank sensor), being in a hurry on a busy street I didn't torque the cap all the way down before I cranked it up - shot diesel all over the top of the motor and into the next lane.

Didn't appreciate how much fuel pressure was there to begin with, got to enjoy the sweet smell of diesel for the next week when I turned the fan on

 

I just talked to a "friend" at my local Ford dealer (luckily only one block from work...where the truck is). He said he could have one of their techs check it out and change the filter while they are at it. That way I can be sure that ALL of the sediment etc is taken care of by a professional instead of my amateur self! and possibly create another problem!

 

D.D. One more thought. Know you have had some cold weather. Could be gelling of fuel which will stop up everything. CA

 

fuel bowl rot on bottom= hole in fuel bowl don't leak if truck not funning.

i mean engine running, hard to type with cast on hand. sory

 

Loose cap. You must make SURE the cap is on tight.

Almost 100% sure.
My 97' PSD did the same thing when i first got the truck.

Just my .02

 

DD, On your sig, your truck is a 97. If you have the original cap that goes on the bowl, they will start to not seal. Mine started leaking and the company that works on my truck, after I screwed something up, put on a Baldwin all in one filter. (Cap and Filter Combo) Hasn't leaked since. I did keep the orginal cap just in case I needed to change the filter with the old style. Its worth a try.

 

Also the rubber o-ring that is included is different in some filters. The one that was in mine was some thing other than Motorcraft, and the o-ring was not seeding. Laeding to a lice fuel leak. Ive read about this all over the place. Chaeper is not always better!!!
