Level Sensor 8–1
Chapter 8 — Level Sensor
Note: NEVER use Teon paste on the threads of the cord grip (power cable) or the threads of
the barbed tting (Equalizer tube) that are connected to the top of the level sensor (or
any plastic part on the pump) because damage could occur! Use only Loctite 598 on the
threaded portions!
Level Sensor Removal
1. Refer to Chapter 7 – Top Housing to remove the top housing from D-Series and IH
pumps.
2. For W-Series, Gatorgrinder and Upgrade pumps, loosen the two rope hooks and
move them out of the way of the level sensor.
3. Disconnect one side of each of the level sensor retaining clips. Separate the columns
and push upward to remove the level sensor.
Level Sensor Test Procedure
The level sensor assembly must be leak tested before disassembly and after reassembly.
The following tools are needed to perform the level sensor test: 1) digital Monometer; 2)
isolation valve with a T or Y tting; 3) hand pump or regulated air source; 4) stop watch; and 5)
three pieces of tubing. These items are available in E/One kit #NB0158G01.
