ABSTRACT:
A tank suitable for holding a lubricant is provided with a dipstick. A sleeve which is mounted on the tank and adapted to support the dipstick is interconnected with the output duct of the tank by means of a further duct. The arrangement is such that if the dipstick is incorrectly located in the sleeve, air is permitted to flow through the further duct into the output duct so that the pressure of the lubricant in the output duct is reduced. This pressure reduction consequently provides an indication of incorrect dipstick location.
