[Gmecm] Vacuum referenced TBI fuel pressure regulator

[WopOnTour]

Since there's no pressure changes at the point of injection (unlike PFI) 
reducing fuel pressure under light loads is unnecessary. If you need to 
raise your fuel pressure you can remove the regulator, grind off the 
brazing, and adjust the threaded factory adjustment.
