6MM 8MM FUEL FILTER GS31185

Function and technical context

This petrol filter is an essential component of the fuel supply system in marine engines, responsible for retaining particles, sediments and contaminants that could clog the injectors or damage the fuel pump. Designed for 6 mm and 8 mm fuel lines, it works by filtering the fuel before it reaches the carburetor or injection system, ensuring that only clean and purified fuel circulates through the circuit. Its preventive function is critical: any impurity that passes through this filter can cause misfires, loss of power, unexpected stops in navigation or irreversible damage to precision engine components.

When to replace this part?

Typical symptoms of a saturated fuel filter include difficulty starting, irregular operation during acceleration, progressive loss of performance and, in advanced cases, engine stalling under load. It is recommended to inspect this filter at the beginning of each navigation season and replace it preventively every 100-150 hours of operation, or sooner if the fuel used has a higher sediment content. Changing the filter preventatively is an economical measure that avoids costly engine repairs and ensures safe, reliable boating.
