Vacuum Solenoid for Secondaries - ZR-1 Net Registry Forums

Finally found the cause for my secondary pump to stay on all the time. Its the vacuum soleniod under the plenum. Neither side holds vacuum. Checked the rest of the system, and everything else does hold vacuum.

The AC Delco part # is 1997222, does anyone know if GM/Chevy still has this in stock, or is it discontinued meaning the only place to get it is from Kurt?
