502 mpi vortec adjustable fuel pressure regulator
Who here has installed one of these and can walk me through the process? Just sent my injectors out to get flow tested and cleaned once i get them back i want to install this and get my fuel pressure exact. Motor is 502 mpi N/A
Ive seen pull the vacum hose off factory regualtor after theres a manuel guage hooked up to the valve on the rail up front but what should my readings be before and after i install this regualtor.
