Airstream 190- Generator Fuel Pump Location?

[kichman]

I am repairing a non starting generator, it has no fuel to the carb.
I cannot seem to figure out where the fuel line goes, behind the 2.8kW Onan genset, or how and where it gets fuel from the main fuel tank. I am repairing this unit for a friend. Certainly there is an electric fuel pump back there somewhere. Also don't know what bolts to pull, to slide out the genset. This one is not on slides. How do you get to the fuel lines and pump?
Thanks for any assistance.

You didn't mention what year the camper is.

In my 1991, the fuel line for the generator is tee'd off the fuel line coming out of the front tank (which means it CAN run the front tank dry). I'm not sure how it interacts with the tank's fuel pump (i.e., whether that pump runs or if the generator's fuel pump just pulls it through). The generator has an internal fuel pump, as I understand it.

I don't know how later years with only one tank are hooked up.
