It is most likely fuel heater in bottom of filter housing. Unplug it on backside of housing and reinstall good fuse and see if it quits blowing. If so, updated fuel heater availible through Ford.

I have f-250 diesel. keeps blowing fuse #22,glow plug controller. what might be the problem


You should start with the glow plug relay/timer.Check it to see if may be shorted.Remove the smaller wires going to it and turn the key back on,if the fuse does'nt blow then replace it,if it does then you need to unplug the fuel preheater in the filter housing and try the key on thing again,pretty sure it's one or the other.
