Troubleshooting & FAQ
How do I confirm this fits my engine?
The best way is to check the part number on your original fuel pump. If it matches 438555 or 433386, this is the correct replacement. You can also verify fitment by checking your engine's HP and year against the compatibility chart.
What are the signs of a failing fuel pump?
Common symptoms include the engine bogging down at high speeds, difficulty starting, stalling, or a noticeable loss of power, as the engine is not receiving enough fuel.
Why does this pump have three connections?
This is a vacuum-operated fuel pump. The three ports are for fuel in (from the tank), fuel out (to the carburetor), and a vacuum pulse line from the crankcase, which powers the pump's diaphragm.
