Submersible pump
Pushes fuel from the tank to the dispensers. Selection depends on simultaneous flow, pressure losses and fuel type. This illustration shows a remote pumping system.

Tank sump and pump head
The tank sump provides containment and access around tank-top connections and the pump head. The motor-pump unit remains submerged in the fuel, not inside the sump. Penetrations require compatible seals.

Tank gauging probe
The probe inside the tank sends measurements to the ATG console. Depending on the model and installed floats, it measures product level, water and temperature. Volume calculations require tank configuration and a calibration chart.
