on the fuel rail. Looks like a silver bell, with a vacuum line attached to it.
Fuel Pressure Regulator is located on the fuel rail.
the fuel pressure regulator should be right on the fuel injector rail
In the alternator.
on the fuel rail to the side
Hi it is located at the corner of the fuel rail open the hood and it is visable it's a round black thing right next to the fuel rail.
It's built into the alternator. Jim
The voltage regulator on a 1986 Buick Skyhawk is located inside the alternator. It controls the amount of power sent to charge the batter based on its current state.
Attached to the end of the fuel rail (pie that connects to the injectors) there should be a round metal thing with a vacuum hose attached to it. This round thing is your fuel pressure regulator. Do not disconnect the vacuum hose with the engine running if you suspect a bad regulator, as fuel may spurt of if the diaphragm leaks and this could be a fire hazard.
I had to have my horn fixed on my 1995 Buick Rivera and it is located under the air bag on the stering wheel. It was an $800.00 expense because they had to replace my air bag.
The tire pressure is located on a sticker on your door jamb.
It's probably the fuel pressure regulator.
weak fuel pump, clogged fuel filter or a bad fuel presser regulator
