Fuel Pressure
What is the fuel pressure supposed to be in an '87 Grand National with everything still stock?

~33-34 PSI with the vacuum/boost line removed from the regulator at idle.

Re: Fuel Pressure
Thanks Keller. Not to seem too dumb, but which one is the regulator?

Re: Fuel Pressure
If you have the stock regulator, it will be a black, somewhat cylindrical object on the driver's front edge of the fuel rail. It will have two bolts holding to the rail, and a drain line coming off the bottom, and a vacuum line on the top. It also will have "BOSCH" in white paint screen printed on the side, along with a part number.

I found the Bosch part you wrote about. Pressure is fine. |
