CAS Regulator Install I just received my regulator from Speed Inc today. I plan to connect the regulator to the end of the billet fuel rail and the the return line. The thing is there wasn't any kind of instructions what so ever with the regulator. Some general install guidance would be great.
Does it matter what end I connect to the fuel rail vs. which end I connect to the return fuel line?
Where should I connect the T for the fuel guage?
How do I adjust for fuel pressure?
Which vac line do I connect to the regulator?
I know these are all basic questions, but I'm not sure of the answers and I don't want to be second guessing myself.
If someone was an installed picture of there CAS regulator please post it.

Re: CAS Regulator Install Here's a pic from my hookup.

I'll try to answer your questions now.....
Check out the picture closely. You can tell where the connections go.
Control of fuel pressure is done by loosening the nut on top and putting in an allen wrench into the hole and adjusting it that way.
As far as the vac line goes....you only need it if your boosted. But it just needs to be referenced from the intake. Put a T into a line off the back and place a line from there to the regulator.
Hope that helps.

Re: CAS Regulator Install Thanks, that picture helped a lot. Mine will be for boost.
You have one fuel line coming from the rails to the side of the regulator, out the other side into a T. Looks like one line is going to a fuel gauge and the other back to the fuel tank.
So it looks like you can use any of the three regulator outlets, depending on your needs and just close off the one you do not use.
Does it matter from which direction the fuel flows into and out of the regulator?

Re: CAS Regulator Install What is the best way to connect the fuel pressure gauge back up, after installing new rails and regulator? Any pictures would be helpful as well.
