i was under the truck looking at the fuel filter. i seen there is a niple on the sensor part of the fliter what is its function? is it some sort of drain? thanks brian

Its a drain to drain water off if the seperator becomes full. The sensor puts a light on in the dash if it is full.

mines never been drained and the light has never come on on eather of the 3 trucks ive owned, i used to try and just fuel came out so i never tryed again,i find it just an other thing in the way when im r&r ing the fuel filter

If you want to drain it, turn the valve open a bit and press on the bleeder pump. Fuel, or water will spurt out. It's best to put a piece of plastic tubing on the nipple first.
