Fuel filter light - Diesel Forum

Can someone tell me where the pressure is measured for the idiot light that comes on when there is supposedly a problem with the filter? I have replaced the filter and have only 2 miles on it and the light still comes on. I am running electric fuel pumps and there is plenty of pressure at the filter head so I got to figure there is something else wrong my system.

Is the pressure there in RUN position....... some guys have accidently put the power wire on a wire that has no power after start or loses it........so check it out.

Where did you hook up too.......try 12volts direct from the battery.

No there is power to the pump as I have a switch to turn it on or off. I have 2 pumps one for each tank.
