Fuel Tank Regulation Inspires New Hose Connectors

Yamaha Marine Group News Release, May 18, 2011

Goal to Reduce Fuel Spills, Spray

KENNESAW, Ga., May 18, 2011 -- As a result of new EPA regulations, changes to portable marine fuel tanks, fuel hoses and primer bulbs will soon affect boat builders, marine dealers and consumers. Consumers should become familiar with the changes in the system components and their operation. They should also become aware of a new Yamaha-exclusive fuel line connector.

Apart from supplying new components that meet the regulations, Yamaha has engineered additional features into its fuel line connectors that are designed to be used with the new fuel system components. With ease of use and security in mind, these fuel line connectors used on Yamaha outboards, portable fuel tanks and hoses will be different from those traditionally used in the industry.

Yamaha’s new fuel line connectors will employ a twist-on locking seal design to arrest fuel flow prior to connection or disconnection. This feature helps reduce the potential for fuel spray or leakage when the fuel line is removed or installed, as the new generation portable fuel tanks may build pressure. These Yamaha-specific connectors are found on both the outboard side and the tank side of the new Yamaha fuel lines.

In addition to the use of low permeation fuel hose, required since 2009, new boats are now using low-permeation primer bulbs (effective January 1, 2011) and for boats that use portable fuel tanks, new tanks must now meet both low-permeation and evaporative emissions standards (effective January 1, 2011). This requires, in part, that the fuel system (tank, lines, and components) be sealed, which may cause them to become pressurized.

On the new tanks, the fuel filler cap will not permit uncontrolled venting of fuel vapor to the atmosphere. Fuel vapor when not allowed to vent to the atmosphere will create pressure inside the tank. The fuel cap remains sealed up to 5 psi before allowing the vent to open and reduce internal pressures. Also, new low-permeation tank material, used in the construction of the fuel tank and cap assembly, is certified to reduce hydrocarbon loss during daily temperature swings (tanks with production dates of 1/1/2011 and later).

New products affected by the regulation are 3-gallon and 6-gallon portable fuel tanks, which are applicable to all Yamaha F4 through F70LA models.

These new tank systems will be accompanied by instructions that outline the correct methods of tank operation. Dealers should ensure correct (matching) components are installed in the fuel system prior to delivery, and the end-user should become familiar with these new components and procedures upon delivery and before leaving the dealership.
