Fuel bowl help

[Gottahav1]

After a short time researching a fuel leak that my girlfriends dad has on his 95 powerstroke, I ordered a o-ring set for the fuel bowl and was wondering how difficult it was going to be to replace all these o-rings. I have not actually been able to see where the leak is coming from because as her cousin was driving the truck it leaked all the fuel out of the tank. I hope these o-rings will fix, the problem but if anyone thinks I might have a different issue feel free to chime in.

Thanks in advance

the switch on the side are bad for leaking also, its called a vacuum switch , that is usualy the worst leak to be leaking that much , if the leak is around the filter housing

If your leaking that much it could possibly be a hole rubbed in one of the lines by the glow plug relay. If it's that you'll have left a line of fuel on the ground.
