Well here is a email from Direct Ford Parts

"The 9G271 you list does show to be correct for this vehicle but the pricing is off. The retail on it is 126.87, your discounted price through us would be 67.25. If that dealership was going to sell it to you for 80.00 then they were giving you a substantial discount anthough not as good as ours. The 9D289 that you seem to think you need sounds right to me but unless you have a Lightning that is the wrong Part number. From what I show you should need # F75Z9D289AA, retail is 32.68, your cost would be 23.10 plus shipping. This part goes from the VMV (Vapor Management Valve) to the intake. Thanks, Gary"

So off I go to locate info on this F75Z9D289AA but whats strange is on their site a search for this part under 2001 F150 doesn't show up. But under parts search for Ford it does.
