FUEL FILTER 907-94469-05 PAF40-0701000EI

Function and technical context

This petrol filter is part of the Yamaha engine's power circuit, acting as a protective barrier between the fuel tank and the dosing elements—carburetor or injectors—in charge of mixing petrol and air for combustion. Installed in the fuel line, it retains solid particles, rust dislodged from the tank walls and organic sediments that accumulate over time, especially in boats that remain idle for months. If the filter becomes clogged or damaged, fuel flow is restricted, and particles passing through it can clog the carburetor passages or injectors, causing misfires and costly breakdowns of high-precision components.

When to replace this part?

A fuel filter in poor condition manifests itself with symptoms such as difficulty starting when cold, progressive power losses when accelerating and intermittent engine shutdowns during navigation, caused by an irregular fuel supply. It is recommended to inspect the filter at each seasonal inspection and replace it at the slightest sign of saturation or visible discoloration; In engines that work with petrol of variable quality or aged tanks, annual preventive replacement is the most common practice. Replacing the filter before a long voyage eliminates one of the most common risks of breakdown at sea and protects the carburetor or injectors from premature wear.
