Where is the high pressure hose connected on the power steering pump of a 1995 buick riviera 3.8 supercharged

If it’s the high pressure side then it will have metal connections on both ends. The rubber hose is the low pressure side. Follow the hose with the metal ends and you’ll find your answer

Where is the fuel tank pressure sensor located in a 1998 Buick Regal Supercharged?


I believe that I can help you.

Go to your throttle body.
  • A large diameter fuel rail is attached to the top of the intake manifold and supplies fuel to all of the injectors.
  • A fuel pressure cap is located on the rail for quick pressure checks,
  • The electric fuel pump is attached to the fuel sender assembly in the fuel tank. It pumps fuel constantly from the tank, through the fuel rail on to the engine and back to the tank.
  • The fuel pressure regulator that is mounted on the fuel rail maintains pressure across the injectors under all operating conditions.
Unfortunately, my scanner is inoperative and I cannot provide you with a diagram

Won't run. Replaced Fuel Pressure Regulator; Engine Computer Module (QDM40; sprayed carb cleanet into EGR; replaced Ignition Control Module. Car runs on Quick Start Fluid only.

If it runs on start fluid and nothing else its obviously a fuel concern fuel pump ,fuel pump relay ,check fuel pressure at the regulator that you replaced.

go into trunk and remove the trunk liner just behind the seats.....pull it towards the back of the car to remove.....look for a metal plate on the passenger side with several screws in it.....this is the access panel for the fuel the 95 riviera you do not have to drop the tank as the manual says......remove panel, disconnect ring that holds pump, disconnect lines and remove carefully......reverse to install....

1995 Buick Riviera supercharged The tachometer is "jumping" and the car is now stalling intermittently. Starter, Battery and Alternator have beren recently replaced. What would cause the tach...

I had the same problem with stalling & found the throttle sensor helped. It was only a $15 part @ an aftermarket parts supplier. You'll need small fingers to get to the few screws holding it in place. Also make sure it's positioned correctly before installing & tightening the screws.
Good Luck!
