Airstream 190 - Genset Fuel pump location??

[kichman]

I am repairing a 190 for a friend, and cannot locate the genset fuel pump. Is it mounted under or behind the Onan 2.8kW genset? I also don't see how the genset is removed, or how the green cover is removed. Almost looks like the unit was installed so as not to ever be serviced. THe docs in the vehicle offer little to nothing tha tis product specific, just the general mounting configurations. Also nothing related to the fuel system whatsoever. I cannot even confirm that the fuel source is the main vehicle fuel tank. Help?
