Also, pull that hose from the booster while the engine is running. It should stall, or at least have a drastic change in RPM because you caused a massive vacuum leak. If it does neither then the boostet vacuum hose is not connected at the engine side. If it does stall or change RPM, then the booster or valve could be bad.
