is there anything I need to know before I change the fuel pressure regulator on my 95 blazer 4x4? and how complicated is it changing it

 

notta big deal if its just the regulator. Remove the crap off the manifold,remove it,then you will see it. If its JUST the reg,i think its a clip you remove then it pops off. replace,then reverse. takes about 2 hours.

 

Mine had two torx screws holding on the reg.
