I used a similar one for many years as seen in Modshack's link. First use was with my boat. Due to limited space (boats do not have space to place a oil pan under the engine) necessitated purchasing one! Their are several manual (vacuum) types and several electric types. Some manual types take less time to create a vacumm. At the track, the manual type is likely the only option. Electric ones can be either 12-volt or household power (120 AC).
Some types can be used for bleeding the brake fluid.
Most marine supply stores stock these.
