A sender assembly that has a compact state, which may allow a pump assembly including the sender assembly to be easily inserted into an opening of a fluid tank. For example, the pump assembly may be insertable into the opening of the fluid tank while a longitudinal axis of the pump assembly remains coaxial with the opening. When in the compact state a rotatable arm and a float of the sender assembly may be entirely within or deformable to be within a predetermined envelope that has a radial extent less than the opening of the fluid tank to allow the sender assembly to be inserted straight into the opening. The predetermined envelope may be coaxial with the longitudinal axis and have a cross-section transverse to the longitudinal axis that matches the opening of the tank.

A fully adjustable liquid tank float incorporates a float for use for gauging the amount of fuel or other liquid contained within a storage tank, the float being connectable to an adjustable lateral arm, which pivotally connects to a vertical structure, which secures to an adaptor that is mounted onto the top of the storage tank. The adaptor connects a transparent housing, which discloses an indicator of the amount of fuel remaining in the tank. The vertical structure is likewise adjustable in length. A flexible linkage connects with the indicator, and is adjustably secured with the lateral arm, to provide for a precise indication as to when the tank is full, partially full, or approaching empty.
