Hello.

The fuel pressure regulator is located under the upper intake manifold plenum and is clipped into the fuel distribution block that houses the injectors. I'll attach some diagrams and step by step instructions for you.

The install procedure is the reverse of disassembly. The torque spec is 80 inch/lbs.

Make sure you get an upper manifold gasket set.
