Help with replacing fuel pressure regulator

I need to replace my fuel pressure regulator on my 96 z28. I was wondering if anybody had a diagram or some instructions on how to do it. Or if I should take it to the shop to have it done professionally. I found the regulator that I need, but does it need a gasket set or an o ring. Any help would be greatly appreciated. Thank in advance.

Here is what you are looking at. Perhaps pulling the fuel rail would make it easier. Pretty sure those are torx screws holding the regulator (10) on. You will also need some fuel line disconnect tools to get the fuel pipes off.

You do not need to release the fuel lines at the quick connects, nor lift the rails.

You need to release the single screw that holds the clamp on the two hard fuel lines at the regulator.... not easy to do, because the screw head is facing down as I recall. Then remove the single screw that holds the FPR to the end of the fuel rail... it is a T27. Then remove the spring clip that holds the hard line into the FPR. Now you can pull the hard line out of the FPR - I THINK there is a small rubber O-ring on the hard line that needs to stay there. Then grab the FPR and twist it back and forth the pull it out of the rail. Again, I THINK there is an O-ring on the FPR, and I THINK the new FPR will have that O-ring (It's been at least 4 years since I ditched the stock FPR and lines). Assembly is the reverse of the above.

Thanks injuneer, im gonna print all your advice out and get to it, I dont like the thought of dripping gas in a hot *** engine, a little unsettling. Do you know what size o ring I need just in case the FPR doesnt come with one? thanks again injuneer and shoebox.

Both the Jet and Aeromotives that I purchased came with the o-rings.

It can be done on the car but pulling the fuel rails does not take long at all and it will cut down on your frustration level.
I did it twice within a week and I would much rather pull the fuel rails.
I installed the Holley AFPR and it did not quite fit like the stock one, no problems but both fuel lines won,t go back into the bracket cause the Holley unit sticks out of the rail a little farther than the stock one.
Just bolt the return line into the bracket and leave the other one where it is, it won,t hurt anything.
Have some rags handy as you will lose quite a bit of fuel, (another reason to pull the rails) the only real problem I had was the wire loom that runs over the top at the back of the manifold I had to push the loom down behind the manifold cause the AFPR was too big to go under it. I also had to relocate the vacuum line as it was not long enough to go around the back of the manifold.
All things considered this piece is pretty easy to install.
