According to my searches and the parts places showing a metal fuel filter for sale, I should have one but can't find it. The engine bay looks to be totally stock and unmolested. I have put the truck on a lift even. I can't see a filter anywhere even though I traced the lines from the tank. The supply line looks to me to go directly into the rear of the fuel rail. I must be missing it. Can someone please point me in the right direction?
