Did you remove the intake manifold?
Did you remove the 8mm bolt?
This part is a dealer item, I just installed two of them this week. Once you remove the 8mm bolt then you must pry tube up. The tube has a oring on the end and that oring is just stuck in intake, I usuallly take one of my large pry bars and just pry it straight up it will come out. Does it have a pin hole in it? Make sure you replace the isolator bolts that hold intake down they are known for sucking air and causing vacuum leaks.
