Replacing engine, can't find hose that connects to fuel pressure regulator on the fuel rail.

Hi,

The fuel pressure regulator requires a constant engine vacuum. On this vehicle, it runs directly to the intake manifold.

If you look below, number 1 shows the regulator, and number 5 is the intake manifold.

Check the manifold itself for the hose.

Let me know if this helps.

Take care,

Joe
