An md-11 air crew received two level one fuel alerts. Approximately five minutes later; the number 2 start valve open light illuminated. They then smelled acrid fumes. They declared an emergency and began divert procedures while running the smoke/fire/fumes checklist and then the start valve light illuminated inflight checklist. They landed; were inspected; and proceeded to taxi in and shut down.

Narrative:
We were enroute to ZZZ on an am morning turn; level at FL380 and direct ZZZ. Approximately 100 southwest of ZZZ we received two level one alerts; tank 3 tip trapped and tank 3 fuel qty lo. The fuel page indicated we had 5;800lbs. Trapped in the right outer wingtip which gave us approximately 3;200 usable fuel in the right wing tank. We referenced the QRH level one alert for the trapped tip fuel and discovered no additional guidance. The low tank warning was a known alert for having less than 3;800lbs. Usable. About that time the tank quantities indicated 7500/3800/8900 respectively. Approximately five minutes after that malfunction we had the #2 start valve open light illuminate. Soon after; while we initially discussed this malfunction; we both smelled acrid fumes; possibly electrical; on the flight deck. We both donned oxygen masks and established communications over the interphone. At that time; we declared an emergency with ZZZ center and determined the nearest suitable divert. Due to both proximity and winds we determined that ZZZ was the nearest suitable divert.we began the smoke/fire/fumes checklist. After completely the initial steps we believed the apparent failure of the #2 starter may well have been the cause of the fumes via the #2 pneumatic system. We suspended that checklist and ran the start valve light illuminated inflight checklist; isolating the #2 pneumatic system.we both remained on masks and proceeded direct the outer marker for the ILS 04R in ZZZ. We checked the mlfl tables for our gw and ran appropriate approach and landing checklists. We landed 04R and exited the runway at 'west' and parked on 'right' for crash fire rescue equipment inspection. They indicated that everything appeared normal. We then proceeded to taxi in and shutdown.
