Oil level sensor guide
A fluid tank system comprises a fluid container that includes a sensor opening in a fluid container wall defined by a rim, and a fluid level sensor comprising a radial flange on a proximate end of a longitudinally extending electronics stem that includes a distal end. The distal end of the electronic stem is inserted into the fluid container via the sensor opening and the radial flange seats on the rim. The distal end of the electronics stem is guided via a first radial support and a second radial support to a seat that is located coaxial with the sensor opening, where the first and second radial supports are longitudinally separated and radially spaced apart to allow the electronics stem to longitudinally pass between the first and second radial supports until the flange seats on the rim ensuring that the distal end of the electronic stem is longitudinally positioned adjacent to the seat.
1. A fluid tank system, comprising:
a fluid container that includes a sensor opening in a fluid container wall defined by a rim;
a fluid level sensor comprising a radial flange on a proximate end of a longitudinally extending electronics stem that includes a distal end;
a guide tube that radially surrounds the longitudinally extending electronics stem and axially contacts a flanged surface of the longitudinally extending electronics stem located within the fluid container, where the longitudinally extending electronics stem, the guide tube and the sensor opening are co-axial about a central axis, the guide tube comprising an inner radial surface which defines a sensor cavity and an outer radial surface, the outer radial surface and the fluid container defining a fluid cavity therebetween, the guide tube further comprising at least one fluid leak hole extending through the guide tube from the outer radial surface to the inner radial surface;
wherein the fluid container comprises a first end having the sensor opening and a second end opposite the first end and wherein the guide tube extends from the sensor opening to the second end of the fluid container and contacts the second end of the fluid container; and
wherein a proximate end portion of the sensor cavity located at the sensor opening has a first diameter and a distal end portion of the sensor cavity opposite the proximate end portion has a second diameter and wherein the first diameter is greater than the second diameter.
2. The fluid tank system of claim 1 , wherein the at least one fluid leak hole is located in the guide tube proximate the distal end portion of the sensor cavity.
3. The fluid tank system of claim 1 , wherein the guide tube is integrally formed with the fluid container.
