Removing the fuel injector rail from the Ford F-150'S4.6L variant is relatively simple, but can be time consuming. Just be sure You don't rush the process, because it's quite easy to damage the components. First, You'll need to remove the two bolts found on the fuELRail. These are 8mm hex. Then, be sure to clean the area thoroughly. I'm a big fan of electrical component cleaner. You'll want to be sure this is spotless before You start prying at the injector clips, because introducing grease to the system is no bueno. Once You get each injector loose (slightly wiggling helps), they should all be able to lift out quite easily. The seal might be difficult to break, but just be careful You don't damage it -- take Your time and don't rush the process.
