I have 93 z and I found out that I have to take off ruel rail to get better access to the egr valve. What do I need to do to get the fuel rail out of the way. Can I just take the 4 bolt out and move out of the way little bit.

 

Yup, just take out the 4 bolts holding down the fuel rail and unclip the harness, prolly have to lift up with a good tug, or use some type of pry bar carfully.
