I'm installing an 04' return-less intake manifold on a 01' truck with an 01' return style manifold. The fuel pressure regulator has a vacuum port that connects to the port on the 01' intake manifold (circled in yellow). The 04' doesn't have this port (circled in red).

Can I T the fuel pressure regulator vacuum line into the vacuum booster line ? Or are there better options out there?

01' style with vacuum port

01' return-style with fuel pressure regulator


04' returnless style with NO vacuum port

Is it an EGR manifold? I'm running the 04' manifold because the EGR really gummed up the 01's inside.

You could use the fitting on the passenger side of the intake. Just break the tab off.

Don't think 03' has EGR. There would be a port on the passenger side right behind the throttle body were the exhaust gases are re-introduced into the intake manifold.
