A fluid level measuring device, also referred to as a dipstick, for measuring the fluid level in a fluid reservoir or tank, such as an oil pan or transmission reservoir in an internal combustion engine. The fluid level measuring device includes a stationary tube assembly in which a rotatable dipstick assembly is disposed. The dipstick assembly includes a fluid level indicator measuring blade attached to an elongated shaft that is molded into a plastic handle assembly. The plastic handle assembly includes a bayonet type locking mechanism for locking the handle to the stationary tube assembly. A compressible seal forms a pressurized seal between the stationary tube assembly and the handle.

The following is claimed: 1. An installation kit for replacing a previously installed fluid level indicator assembly comprising: a sleeve comprising a first end associated with a threaded area and a compression fitting, a coupler that engages a second end of the sleeve wherein said coupler has at least one lug extending therefrom, a handle comprising at least one slot wherein the slot comprises a generally axial portion and an axial portion and wherein said at least one slot engages said at least one lug, a shaft rotatably associated with the handle; a compressible member located in the base of the handle that engages at least an end face of the coupler; and, a compression nut that engages the threaded area of the sleeve wherein the compression nut is received upon a tube of the previously installed fluid level indicator assembly. 2. The kit of claim 1 wherein said at least one lug is outwardly extending. 3. The kit of claim 1 wherein said at least one lug is inwardly extending. 4. The kit of claim 2 wherein the shaft comprises wire. 5. The kit of claim 2 wherein the compressible member seals against the end face. 6. The kit of claim 1 further comprising a fluid level indicator blade attached to the shaft; and wherein the compressible member comprises a face for engaging the open end of the coupler and wherein the compressible member urges the handle toward a locked position. 7. The kit of claim 1 wherein the sleeve has a knurled section adjacent to the first end of the tube for receiving the coupler. 8. The kit of claim 1 wherein the compressible member provides a seal of capable of maintaining at least 1 atmosphere. 9. The kit of claim 1 wherein said compressible member comprises an annular seal that urges the handle and coupler into a locked position that is achieved when said at least one lug engages a locking seat.
