Good To Know

Q: How do I know this pump matches my engine? A: Compare the OEM number on your old pump or in your parts list against 808492, 491922, 808656, 691034, and 692313. A matching number confirms the correct replacement.

Q: What causes a fuel pump to fail on these engines? A: Worn or hardened diaphragms and contaminated fuel are the usual causes. Replacing the pump restores steady fuel flow to the carburetor.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
