Product Overview

A generator that starts and dies, surges under load, or has no fuel at the carburetor may have lost pump output. This 12V electric pump supplies fuel on Onan generator sets using the 149-2583 design.

Before replacement, verify power and ground at the pump, tank pickup, filter, hose condition, and fuel quality. Some Onan models use other pump pressures and fittings.

Frequently Asked Questions

Q: Can a fuel pump fail only when hot? A: Yes. Some electric pumps lose output as the coil warms.

Q: Will this fit an Onan 5500? A: Only if that exact generator specification calls for 149-2583 or a listed matching reference.

Q: What else causes start-then-die? A: Low oil shutdown, carburetor faults, controls, filters, tank venting, and ignition can cause similar symptoms.

Q: Is it genuine Onan? A: No. It is an aftermarket replacement.
