1999 Ford F-150 Coil On Plug

Dave H. Just identified the Coil On Plug for me. That is very helpful in the removal of the correct part, however I also see a (aluminum I believe) tube that may be blocking the COP, the tube connects to 4 other parts (fuel injectors I think) that go into the engine block. Do I need to remove the tube to get to the COP, or will that damage other parts?

Also, I want to make a small donation for the information I am receiving, how do I make the actual donation?
