Onan wants us to use a pump that serves as a positive fuel line shutoff when NOT running. Some models had a Pump that was NOT shutoff and there was an extra solenoid valve to accomplish this. Here at Facet-Purolator the specs on LOW pressure pumps include whether they are shutoff or not. I replaced an old Facet type solenoid pump with a little aftermarket one (labeled only "Purolator" back then). It worked fine and never caused a problem by NOT being shut-off. The risk would be that the coach's fuel system would pressurize the genset's carburetor and the Float Valve wouldn't hold, letting it flood over.
All that said, Amazon offers pumps that are a direct match to many Onan applications, reasonable price and no need to improvise. They actually looked less expensive than improvise, HERE.
Yeah, Where's the Fun in That?
The caution I would give with fuel pumps is to make sure the flow rate is at least and close to original and the psi is within 2-3 psi.
I have a post somewhere I recently updated with a pump I just used on an Onan, with the specs.
