Product Overview
Consistent low-pressure fuel delivery is important on carbureted generator and small-engine systems. A pump that becomes intermittent, weak or noisy can cause extended cranking, fuel starvation under load or random shutdowns even when the carburetor itself is in good condition.
This unit is sized for 12V systems and the 3.5–5 PSI pressure range associated with the listed Facet and Onan references. Match the electrical connection, inlet/outlet orientation and part numbers before installation.

Frequently Asked Questions
Q: Can I substitute a higher-pressure pump?
A: Use the specified low-pressure range. Excess fuel pressure can overwhelm a carburetor needle and seat and cause flooding.

A: Match the original part number, voltage, pressure requirement and port/terminal layout.
