It's a grommet with a fixed orifice. The orifice comes with a tube at Napa. The grommet may be sold separately?

Especially if you get one and do this:
Complete tuneup with new NGK plugs, new wires cap and rotor.
Check intake manifold bolts to be sure they're tight.
Repair or replace vacuum harnesses as needed.
Do Tips 1 through 5 right off the bat.
