SUZUKI GASKET 13421-98J00

Function and technical context

This gasket is part of the fuel supply system of the outboard engine, acting as a sealing element at the junction between components of the injection or carburetion assembly. Its mission is to ensure that there are no fuel leaks between the parts it seals, avoiding both performance losses and flammability risks on board. A deterioration of this gasket can result in a loss of pressure in the fuel circuit, unstable idling, difficulty starting or, in serious cases, petrol dripping on the engine block, with the danger that this entails in a boat.

When to replace this part?

The most common symptoms that this gasket has lost its sealing capacity are the smell of fuel in the engine compartment, petrol stains in the area of the injection system or irregularities in the operation of the engine at different speeds. It is recommended to inspect the condition of the fuel circuit gaskets at each seasonal inspection, since the cyclical heat and chemical agents present in modern fuels (especially those containing ethanol) accelerate the aging of the material. Replacing this seal preventively during scheduled maintenance is significantly more economical than facing a breakdown or emergency intervention in navigation.
