The $50 pumps look just like the onan pump, but they don't seem to last very long. Is the Onan pump really worth the $260 they cost?

It's the government-mandated ethenol that kills the pumps. I doubt an Onan pump would do any better.

To get the code, press the stop/prime button 3x within 5 seconds. It'll then blink a single digit. Press it one more time, and it'll blink a two-digit code.

A fuel pump problem will generate a generic 36 - which stands for fuel delivery problem. Could be a pump issue, low fuel level, leaking fuel line, gummed carb, or anything else that causes the genny to starve of fuel.

It's probably one of the more common codes.
