The motorized pump is disposed to pump fluid from the lubricant reservoir to lubricant work lines. The follower plate is situated within the lubricant reservoir. The stationary rod has a colored indicator portion. The movable sleeve disposed concentrically about the stationary rod. The flexible connection extends between the follower plate and the stationary colored rod, such that the flexible connection pulls the movable sleeve away from the stationary rod to reveal the colored indicator portion as the follower plate drops towards a bottom of the lubricant reservoir.
