Problem with Aux fuel throwing circuit breaker cb1 mep-802a

[ribs1]

OK,
So, generator runs fine on main tank. When I set it to aux fuel it sometimes runs for a while then trips cb1
After this it will throw the breaker as soon as I turn the main switch to aux prime and run. Pump runs for about 2-3 seconds the circuit breaker trips.
Thanks for any tips

I'd pull off the rear cover to access the fuel pump.
Unplug 1 item at a time and retest to observe when the problem goes away.
Start with the pump itself.
If the issue remains, unplug the dual float assembly ( if you're unsure of what I mean just ask )
If the issue still remains, unplug the float control module mounted to the right of the tank when looking at the tank.
Let us know what results you get.
