99 7.3 Fuel Leak

[MRT6453]

Hi all,

I have a 99 7.3 diesel. I replaced the fuel filter and noticed a leak right away(front passenger side) and a little rough idoling. After reading many forums I figured out it had to be the seals in the release valve on the back of the bowl. I replaced the whole valve. Drove to work and as soon as I got to work diesel was coming out of the front passenger again. Looks to me like the over flow tube but I could be wrong. Does any one have any ideas for me???? Any help would be great.

Did you put the o-ring on the lid the right way?

Make sure the leak is not coming from the lid.

Is the drain valve for the fuel bowl closed all the way? If the motor is running ruff after a fuel filter change or it ran out of fuel once it gets started again hold the RPM's at 1800 right away for a couple of minutes untill the lines get bleed out.

2005F250 and POWERSTROKER1---- Yes the valve is closed all the way. There is no leak coming from the bowl or valve at all.

Is there a way for diesel fuel to mix with the antifreeze on a diesel? I ask becuase I leaked some antifreeze out of the cap and it smells of diesel pretty bad.
