Went out this morning first thing , cranked my truck, switched to high idle(first cool morning we have had-55) to warm it up, and was going to take the trash off. After a few minutes of listening to my "jet Engine" I smelled fuel. Got out, saw puddle under truck, Checked engine valley-no fuel anywhere. Found fuel was coming from drain hose(fuel filter). Shut off truck ,leak stopped. Cranked truck-leak started again. Open and shut the valve-no help. Ran back in the house, Fired off the dinosaur(computer we have) and hit the forums in full blown SEARCH FUEL LEAK mode. Found thread, read it, called dealership, picked up new valve, Started changing it out, Said some words I didnt know I knew, Finished the change, Busted the engine off, and whata ya know- NO MORE LEAKS. Dummy like me would have paid 150 to get that done, but with the help of these forums, I gotter done and saved some money. Keep on posting your problems guys and then come back to them and post the fixes. It helps all of us learn. Thanks to the forums!!
