ABSTRACT:
A hand-manipulative apparatus is disclosed for receiving a specimen of the fuel tank contents of a fuel tank. The apparatus comprises an elongated body of substantially circular cross-section. The body is fabricated of transparent molded material and is open at its upper end. The body is of tubular character through a portion of its length for defining a fuel-receiving compartment having a central axis and communicating with the open upper end of the body. The body has spaced-apart indentations in its upper end edge for alignment and cooperation with associated actuating arms of a pet cock drain valve, if such a pet cock drain valve is utilized. The tubular portion is closed at its lower end portion. A resilient semi-rigid rod is removably attached at a first end to the lower end portion of the tubular portion. The resilient rod extends along the central axis beyond the upper end edge of the body so as to engage and manipulate a ball and spring drain valve at a second end of the rod, if such a ball and spring drain valve is utilized. Additionally, the rod is supported at an intermediate portion thereof. Supporting the rod at the first end (lower end) provides much more effective use with ball and spring type drain valves making it much less flimsy and incapable of being pushed down the elongated body during use by the opposing force of the ball and spring valve.
