Directional gyro; altitude indicator; vacuum failure; strong smell of smoke and small amount of visual smoke from instrument panel; declared emergency; turned to airport; turned off non essential electronics and ventilated cockpit. Was cleared by approach to land and handed off to tower. Landed straight in; advised tower that smoke had cleared from cockpit and was advised if able to taxi to ramp. Taxied to FBO with emergency vehicles following. Once clear of the txwys exited aircraft and checked engine compartment for any fire hazard. A mechanic checked the aircraft and determined smoke and smell came from the sheared vacuum pump. Emergency personnel on site declared emergency over. Callback conversation with reporter revealed the following information: the aircraft type was a PA28 that had flown about 150 hours since the engine had received a major overhaul. The vacuum pump was replaced at that time and the reporter believes that it must have been defective. The decision to land quickly was influenced by a recent fatal accident the reporter was familiar with; in which the decision to land was delayed.
