Gas Tank
Go to www.ford.com then select Owners...(www.fordvehicles.com/owners/)... and register your truck by creating a MyFord site. All it requires is your VIN. From there, select Resource Center on the left, then Owners Guide and you should see choices of the various owners manuals for your truck. The manuals I can access are shown below.
