I have a 93 f250 with a 7.3idi motor. I noticed today my Fuel Filter check light didn't come on when I started the truck. Where is this sensor located? thanks guys!
Well that is the water-in-fuel sensor, but there is also a fuel filter sensor on top of the filter housing. It looks like a small version of the oil pressure sender and points towards the middle of the engine.

The filter sensor will set off the WIF light, right? It must because my WIF sensor is unplugged and the other day I got a WIF light. I changed the filter because it most likely needed it and the light went away. Unfortunately now I am having fuel delivery issues most likely caused by leak back. No leaks anywhere and the truck started on the first crank before changing the filter. I don't get it.
why would someone plug my continuous vent with check valve and what does the schraeder valve do?
probably because it leaked and was the cheap and easy fix to just plug it by a previous owner.
the schrader valve lets you bleed air,and take fuel pressure readings.

the bottom sensor will yes.if the sensor is unplugged and shorts to ground it will set off a false reading that you have water in your fuel.
plug it back on and drain it every 5k miles or whenever the light comes on.whichever comes first.
the fuel filter should last 60k miles or whenever the top fuel sensor triggers your fuel filter light (not the same light as the WIF) whichever comes first.
