Gen set not getting fuel

[Bukrub66]

I just bought an older Roadtrek with an Onan 2800. The previous owner said he had never used the Gen and it only has 102 hours on it. I figured the carb was gummed up, so I dropped the bowl and pulled the filter. Filled it all up with carb cleaner and it fired up for just a second. I pulled the fuel line and tried to crank it, but Im getting no fuel out of the hose. In looking at the Gen manual it mentions a fuel shut off, but for the life of me I cant find it. I assume if there is no valve, it must be a fuel pump. Any idea where a shut off valve would be on a 93 Roadtrek 210. Not sure how I would even get to the fuel pump thru that small door.
