What is the normal fuel line pressure for a '96 GMC Jimmy 4.3L?

Hi,

 

 

That is actually too low- new fuel pump is defective. With key on, engine off, fuel pressure should be 55-61 PSI.

 

On yours, the fuel pressure regulator is located on the "spider" injector assembly underneath the upper intake manifold
