Hey guys,
I attempted to change my fuel filters today (05 PSD). My understanding, per the above directions, for the primary/chasis fuel filter is to remove the drain plug on the HFCM to let the diesel in the housing completely drain before changing the filter. I started this and set up a funnel to catch the fuel and drain in my basin (no big deal). It seemed to take a while to drain, the fuel just kept trickling. So, to keep from making a mess i was patient and just let the fuel continue trickling out and went ahead and cleaned my airfilter. Well about a 1 hr later, the fuel was still trickling out of the HFCM plug and I had about 2.5 gallons of diesel fuel in my basin. Again, how much fuel should drain out of this thing? I thought it would just drain the volume of the housing?? And once completely drained you could change the filter. Any input?
