96 blazer: fuel system..tank..told It was the pressure regulator

Resolved Question:

I have a 96 blazer with CSEFI fuel system. With key-on engine off, the fuel is bleeding back into the tank. Was told It was the pressure regulator because it holds 61psi when started and running. Just to clarify, can I replace just the pressure regulator or do I have to replace the entire unit, injectors and all?

The fuel pressure regulator can be replaced separately. Remove the upper intake plenum to access the regulator. A small clip holds it in place.
