I try to Service my truck today, and as alway there something that get you. I also change the oil no problem there. I got under the truck and pop the fuel drain plug out and drain the HFCM. Went to put the drain back in and I notice that o-ring was bad. Ford dealer told me that you have to buy the hold plug not just the o-ring, and there in nun in stock at the two dealer I called . I try call the two International dealer and nun in stock have to wait till tomorrow to get one in. you think that they would stock it. So the Truck is sitting for the night. Just venting Thanks for understanding.
