Mep 803 Auxiliary fuel question

[Kemp3]

I am wondering how these units handle the aux tank running out of fuel ? is there a safety built in to protect the aux pump ?

thank you

Theoretically it will continue to run and run, because the float setting will not be satisfied to shut it down. You will need to understand fuel burn (GPH) compared to fuel quantity, to know when to check before empty.

I was worried about that . I think I can use a float to open the aux fuel pump circuit when low enough.

What is the install scenario you are trying to work around?

The float assembly in the tank that controls the aux fuel function has two floats, with high level and low level magnetic contacts. When the lowest float hits its determined level, it turns that circuit on. And when the high float is raised by new fuel, it opens the circuit, disengaging the aux pump.

I've foreseen a similar need when feeding the generator with a few extra gallons from a Jerry can. I've considered putting a remote AUX kill plug on the back near the aux input that connects to a remote float switch. Not a huge technical lift.
