Thanks AL. My FSM shows the above but there is a cover retaining the fuel lines going into the fuel rail and regulator and I could not make out if the tool was needed for disconnecting the line from the regulator.
Again. Thanks.

Shouldnt need that tool at all by the looks of it

not trying to hijack, but how much of a pain is it to disconnect the line from the bottom of the FPR?

Just did the FPR change today and it is not hard to pull the lines off the FPR. Just take off plate that hold them in place and pull and wiggle and out they come but make sure you have a bunch of rag to catch the fuel that will come out. The hard part is trying to get the star socket and ratchet to fit and unscrew. I had to take off the fuel rail to be able to remove the old FPR and replace it with the new one.

Today I did the FPR install. Time consuming task, had to remove the fuel rail in order to get the star socket and ratchet extension to fit cause the line is somehow curved around the FPR and cannot fit in the socket and ratchet by themselves. I replaced the vac line from the FPR to the intake and add new connectors for precaution. I also sprayed the intake with TB cleaner until it loosened everything and let it drain on a rag. I also took the time to clean the MAF with maf cleaner and I can say it seems my Z is back on the road running smoother. I took it for a long ride and not issues. Let it sit for 2 hours and started it up again and it lit up without any extra cranking. Knock on wood, hope nothing else goes wrong. This car is truly a love and hate type of thing. I love to drive but hate to work on it.
Thanks to all that helped along the way.
