2003 GMC Sierra Fuel Pressure Regulator?
 

I think I may have a bad Fuel Pressure Regualtor but don't where it is located on the vehicle. My vehicle is a 2003 GMC Sierra 2500 HD. It has the 8.1L engine. Can anybody point me in the right direction?

Thanks

On the driver side of the intake manifold, on the hard line fuel rail you will see a diaphram lookin part with a skinny vacum hose hooked up to it. Looks like this...http://www.autozone.com/autozone/cat...sure+regulator
