PUMP AND FUEL LINE 6MM X 2 METERS

Function and technical context

This pump with a 6 mm and 2 meter long fuel supply line works within the fuel supply system in Yamaha 2 and 4 stroke outboard engines, being responsible for moving the fuel from the external tank to the carburetor or injection system. The 6 mm diameter ensures a constant and sufficient flow rate to maintain the propeller demand in any navigation regime, both at idle and at full load. A deterioration in the pump or a microcrack in the line can interrupt the flow of fuel, causing sudden power losses, unexpected engine stops or starting difficulties that compromise the safety of the boat and its crew. The 2 meter length allows direct installation without intermediate splices, minimizing possible leak points in the power circuit.

When to replace this part?

The most common signs of wear on an outboard fuel pump are difficult cold starting, rough idling, jerking under acceleration, and progressive loss of maximum power; in the line, look for signs of hardening, surface cracking or microporosities that could cause fuel leaks. It is recommended to visually inspect the line at each seasonal tune-up and check the pump-line assembly every 100-200 hours of use, replacing both elements preventively in the event of any sign of material aging. Replacing this assembly before it fails in navigation avoids unforeseen immobilization and costly emergency interventions at sea.
