I don't know if I can help much as I've never had problems with our 2010, and especially after you said that others had already tried. However, you referenced the pump and stuff facing the generator, so I'm presuming that your unit has the generator box built in. In our 2010, our generator prep box has an access hole through which one can work with the pump.



I suspect that if others have worked on your unit, they may have already found that small access cover on the right in the picture above. If not, maybe your unit has one as well.
