I always do my own work but I had a gift card to a dealership. I took my 03 flex fuel in for an oil change, tire rotate, and fuel filter (Which I supplied since I had a Fram laying around). I talked to the tech when he done and he told me that he couldnt get the little plastic snap lock on the nipple to work so he took it off. Is this ok??? I got under the truck and could not pull the fuel line off the filter but Im a little scared that the piece was needed. Am I ok?
