I always assumed that the 'Change Fuel Filter' message was simply based on a preset mileage counter, but an experience yesterday leaves me wondering if it isn't 'smarter' - i.e. reading a drop in fuel rail pressure. In the morning, the message came up at startup. Hadn't seen it before, but it made me consider the mileage on that particular filter, which was approaching 15K.
By that afternoon, immediatly after a re-fill in southern Illinois, I got an SES light and limp. Read the code with the Predator, sure enough low fuel rail pressure. Reset the code and resumed a safe highway speed with the oversize boat, until a suitable exit was found. After changing the filter, the message alert has disappeared, without any pedal-dance to reset the indicator.
Maybe this thing is smarter that I thought...?
Also - I carry a strap wrench, but never need it. Mechanix Gloves and the red aluminum tool for removing the WIF sensor is all thats needed, if you only twist them hand tight. A good trick learned from JK. When re-priming, I use the rounded end of the red tool into the dished top of the primer button, gaining some advantage by using both hands to drive the button down firmly until fuel is seen at the breather. Saves on sore fingers. I can usually do a filter with zero fuel spillage under the hood, and be back running in the truck in about 10 minutes - a little longer if its -10 below...cussing takes time.
