I assume your float was twisted a little and the float was binding up against the side of the tank?
I think so. Not totally sure. I took the float out and tested it's function while my wife started the gen. After that I was sure the float was ok. Reinstalled the float and made sure it seemed to have good clearance. Now all is good.
Hello Again,
Since I got this repaired I have not tested the aux fuel until today. The unit is shorting again when I connect to aux fuel and try to prime. The aux fuel prime does work when not connected to the fuel drum. When connected to the fuel drum it shorts. I replaced the dual float assembly last year. I might just give up on using aux fuel and just fill the tank but it would be nice to be able to connect and use my drum. Looking for opinions. thanks

You say it shorts out. Tell us WHAT it does when it Shorts out.
Have you tested the AUX fuel pump- Its simple. Un plug it. The plug has two pins. Apply 24 VDC to the two pins. It works or it arcs .

Hello, it throws the cb1 breaker. I have not tested the pump itself. This only happens when the fuel line is connected. When fuel line is connected to fuel drum it trips the breaker. When fuel line is not connected the aux pump will run when set to prime.

Other than the Hello, this is just what I wanted to know. But I guess you know more about this than I. I wish you luck in the repair of this set.

I'm sure I don't know more about this than you. Sorry about the wording, I came in to check your message then had to go right away. Thanks

Perhaps I am just being a curmudgeon tonight. Old an in the way. Sorry too.
Is the gen set grounded?
Is the hose you connect to the Aux input fitting, and run to the Aux fuel source, a military hose? The reason I ask is that the military hose has braided steel wire in it. The brass fittings on the ends of the hose screw into the hose, and make contact. So the hose can in theory, conduct voltage. Is the end that goes to the fuel source, the input fitting, insolated from the fuel tank? Or is anything else hooked to the tank?
Take the end off the fuel source, Put the S1, (start switch) in the AUX prime position. Take the free end of the hose and touch something that is grounded. CB1 pop? If not, then touch the hose to the fuel inlet fitting on the fuel source. CB1 pop?

Does it trip the breaker the nano second that you trigger it, or does it get a couple or few pumps in, then trip?
Even if the pump runs with no load on it, it could be on its way out. Increasing the load(amps) on the pump by drawing fuel out of a drum could be a potential culprit as well.

Try pumping out of the main tank with the aux pump.
Hello. Thanks so much for your help. The hose is the correct military hose. The genset is grounded. It's connected to the house. The ground wire goes into my transfer switch and then to house ground. I'm not sure about the second question. The input connects into the standard dip tube usually used with this set and into a 30 gallon steel drum sitting on the ground. Nothing else is hooked to the drum
I will try your procedure in the morning to test this.
Thanks again so much for your help.
