Why would the aqua hot fuel pump be running
Tonight I heard a motor sound and found the aqua hot fuel pump running.
Haven’t done anything other than turning on 12 volt master to do some cleaning to the new to me coach.
Never heard the pump run the numerous time there last couple days cleaning

Perhaps there is a leak or its sucking air. The pump is trying to satisfy the pressure switch.

The Aqua Hot fuel pump is run by a gear on the blower motor shaft. So, if the fuel pump is running, so is the blower motor and exhaust air is coming out of the exhaust pipe.
If the blower motor is running for more than 3 minutes after the firing has stopped, you have a failed control unit.
You may call me before 9 pm central time and I can assist you diagnosis the issue. Or anytime Saturday after 8 am.
