I have a Newmar gas coach and I know the onan 7.0 generator has an automatic cut off when the fuel tank reaches a certain point (usually around a quarter of a tank). My question is can that cut off point be adjusted or turned off? My problem is we use the generator while we are running and it's very frustrating to have to pull up for gas with about 1/2 to 3/8's of a tank of gas still in the coach because the generator has shut down. I understand why it has a cut off to avoid running out of gas while dry camping but we hardly ever put ourselves in that position and really would like to see the reserve shut off closer to an 1/8th of a tank. Any thoughts?
