Abstract: A connector for a fuel gauge in a fuel cell which has an inner tube (12) and a spaced-apart concentric outer tube (14). A housing assembly (16) is mountable to outer tube (14) and includes a contact (19) electrically connected to the outer tube. A sleeve assembly (25) is slidably mounted in a bore (24) in the housing assembly and extends through an opening (29) through the outer tube, and a first end (32) of a contact assembly (26) within sleeve assembly (25) extends through an opening (35) in the inner tube and self-secures thereto. The contact assembly of the sleeve assembly makes electrical contact with the inner tube (12) at opening (35) and is connected at second end (33) by an electrical lead to the fuel gauge. An electrical lead also connects contact (19) connected to outer tube (14), to the fuel gauge so that an electrical potential between the inner tube and the outer tube may be measured.
