Hey i have a 97 f 250 with the 7.3 and fuse #22 under the hood blows once a day maybe more or less. The circuit has to do with the fuel line heater,glow plugs and more anybody every have a problem like this. Open for suggestions plez

 

Try first unplugging the fuel heater on the backside of the fuel filter/water seperator.. See if the fuse continues to blow.. Fuel heaters fail/short andare common cause for the fuse to pop..
