I figured now would be a good time to change the fuel filters being its double the typical mileage. Stock is suppose to change out at 15,000 miles or every other oil change. Here is what the stock filter and the Donaldson P551315 looks like after 30,000 miles of fuel pumped through them.I must be getting clean fuel because I was totally expecting after 30,000 miles I would be look at a AirDog filter that was black and the stock filter about the color I see now. But I was shocked to see both rather light colored. Now I know to just use my fuel pressure gauge and look for the fuel pressure drop. Because both of these could of gone farther yet and still in good condition.
