Have a 2002 S-10 Blazer with about 38k miles and I want to replace the Fuel Pressure Regulator. I have all the bolts, electrical hook ups, throttle body, distributor cap, hoses, fuel lines OFF on this darn thing and the PLENUM in take will NOT come off. I can get it about 1/4" up off the manafold below it and move it around some, but is seems to hanging up on something towards the back underneith of it. Any help is appreciated. THANKS:banghead:

The injection spider assembly - after you unplug that big connector to it the assembly under the upper intake has a large o-ring on the oval that is tight to maintain a good seal and no vac leaks so it should pull right up and off - and it will allow the upper intake to move around cause the assembly is in a very loose holder that allows self centering on install (or its another quality GM fit your option!) - this all assumes you got all the wiring unplugged.
