SUZUKI FUEL FILTER 15410-88L00 REC15410-88L00

Function and technical context

The petrol filter is part of the fuel supply system of the outboard engine, acting as a retention barrier between the tank and the injection or carburetion system. Its mission is to intercept solid particles, corrosion residues and emulsified water that may circulate with the fuel, thus protecting the injectors, the petrol pump and the needle valves from clogging and premature wear. In four-stroke engines with direct injection such as the Suzuki DF40A, DF50A and DF60A, fuel cleanliness is especially critical: any contaminant that reaches the high pressure circuit can cause injection failures, power losses or unexpected stops while navigating. Keeping this component in correct condition is one of the preventive measures with the greatest impact on the reliability of the propeller.

When to replace this part?

The most common symptoms of a saturated or degraded petrol filter are difficult starting when cold, loss of speed at full load, irregular idling and sudden engine stops under power demand. As a general rule, it is recommended to replace the fuel filter every nautical season or every 100-200 hours of operation, adapting the interval to the quality of the fuel used and the storage conditions of the boat. Renewing it preventively before each season eliminates one of the most common sources of avoidable breakdowns at sea.
