Things I learned today. Getting ready my trip south I had the dealer change the oil and filters in the truck. Including the fuel filter. A week later I am doing a transfer from my auxiliary tank and it's taking forever. I have a Titan Trekker 50gal bed tank that sits below my tonneau. I love it. I called them on the phone and without hesitation they asked if I had ever changed the inline filter. Uhhh no. Its now added to my maintenance list and an extra onboard for emergency. $7.00 for peace of mind.
