This pass fall my fuel pressure regulator went bad on my 91 vert and I know taking off the upper intake off would be the easiest route.... I was just wondering if I would need anything else other then the intake gasket and if anyone had any tips or stuff look out for.... Also how long should it take

ALMOST STOCK

Removing the upper intake depends on you mechanic skill level but even as a beginner it shouldn't take you any longer than 30-45 mins
to remove the upper from the lower.



Remove the 4 Torx screws on the cover to access the 2 long bots underneath cover.
Unhook the plastic clip holding the 10 pin connectors
Remove the 2 long 5/16 bolts under the cover
Remove the 4 smaller 5/16 bolts on the ends of the upper intake.
Disconnect the 3 inch hose to the throttle body and move out of the way
Disconnect the electrical connection to the throttle body and EGR valve
Disconnect the vacuum line to the EGR
Now break loose the upper intake from the lower and remove , sometime breaking the seal of the gasket from upper to lower can be a pain.
Ease the upper up and remove the vacuum lines on the underside of the upper intake.
Large rubber hose to Source on large vacuum T on firewall.
Thin Black plastic line to rubber 4 port emissions near the passenger side strut tower.
Thin RED vacuum line to Fuel Pressure Regulator


Change your fuel pressure regulator


Install new upper intake gasket
Reconnect vacuum lines to underside of upper intake
Torque all 6 bolts (4 SHORT AND 2 LONG ) to 12-18 Lb Ft
Reinstall electrical connections and hook up EGR Vacuum line
Hook plastic 10 pin connector clip back up.
Reinstall and tight 4 Torx screws.




Side Note:
It depends if your upper has ever been remove before or not and if it has did someone remove and throw away a metal bracket that attached to the back of the upper intake and the opposite side to the lower intake. See attached
If that bracket is still there then on the back corner of the upper intake there is a stud with a nut that you'll need to remove ad then remove the lower bolt so that you can remove the metal bracket and have access to the nut on the stud of upper intake. see attached diagram
