I have two injectors that leak and am getting ready to replace them. Any hints as to how to do it? Parts store I where I bought injectors sold me parts that require taking off the top part of the injector.(i.e. overflow & fuel line end) Is this right? Also, what size deep socket is used for the injector, 29 or 29mm?

This is my first posting and I wanted to thank you all for the good tips I've already picked up just watching!
