FUEL PRESSURE REGULATOR location on a SPFI


Recommended Posts

Fuel pressure regulator is on the side of the throttle body - it's vacuum source is on the backside about 2" away from the regulator. There are two types of regulators - one is black, and one is gold. Both are interchangable.

 

The hose from the regulator goes to the return line - the line from the throttle body goes to the fuel pump.

 

Or are you asking about the fuel pump oreintation? The big end is the supply, and the small end is the pressure end that goes to the engine bay.
