6 Volt Fuel Pump

[Lang]

Another comment on return lines. If you do put in a return line and the pump can keep up with both the engine supply and circular return flow it will be running flat out continuously and will certainly fail before its allotted four score and ten years.

On the gun tractor fuel diagram you can see a little "bell" on top of the pump. This is the pressure sensor and as the diaphram rises and falls with the fuel pressure it makes and breaks contact with the pump motor.
