TUBE CF10x5x300 90445-09105

Function and technical context

The CF10x5x300 tube is an essential component of the fuel supply circuit in two-stroke marine engines, responsible for guiding the fuel from the tank to the carburetor with precision and safety. It works in the low pressure system of the supply line, where it is constantly exposed to temperature variations, continuous movement of the vessel and prolonged contact with fuels that can be chemically aggressive. Its structural integrity is essential to maintain optimal pressure and flow in controlled fuel injection; Any leak or entry of air compromises the reliability of the engine and can cause significant loss of power.

When to replace this part?

Typical symptoms of deterioration include visible leaks at the connections, hardening or brittleness of the tube due to oxidation and exposure to ultraviolet radiation, as well as loss of power or difficulty in starting due to air suction in the supply line. It is recommended to inspect the condition of the fuel tube during each seasonal maintenance and replace it preventively every 2 to 3 years or when it shows obvious signs of cracks, porosity or material detachment. Preventive replacement is a recommended practice that prevents emergency repairs at sea and ensures reliable and safe operation of the power system.
