According to §2853(a)(16), all fuel hoses from the watercraft fuel tank to the first attachment point on the marine engine must to be certified. Fuel hoses that are installed on the engine itself, such as hoses running from a fuel rail to an individual fuel injector, are not subject to this fuel hose certification requirement.
Yes, a single canister can be used for multiple fuel tanks as long as the canister is designed to control the total volume of fuel stored in those tanks and meet the applicable standard. For example, a canister that is certified for use on tanks up to 50 gallons may also be used on a fuel system that consists of two 24-gallon tanks.
Yes, worst case carbon canisters are defined as the lowest length/diameter (L/D) for the evaporative family. A canister evaporative family is defined as all canisters using the same carbon and same cross section design with the only difference being the length of the carbon bed. The emissions test results can scaled on a carbon volume basis to arrive at tank size ratings for the other carbon canisters in the same canister evaporative family. The canister dimensions and associated maximum fuel tank size for each canister model must be submitted as part of the component certification application package.
No, the SIMW regulation requires that all testing must be performed by an independent laboratory according to §2856(a)(3)(D). Independent laboratory is defined per §2853(a)(18). Note that the durability portion of test procedures can be performed in-house, but the test data must be generated by an independent laboratory.
All vehicles that comply with California regulations have a Vehicle Emissions Information label on a visible location on the vehicle. In addition to listing all equipment used on the vehicle to comply with California requirements, the label lists the vehicles test group or Engine family Number. This number can be cross referenced on our website by checking the Executive Order for the year make and Test Group.
New vehicles that have not yet been registered will also have a Manufacturers Certificate of Origin that will state the standards that the vehicle complies with and list the manufacturers legal name so that you can cross reference that information with the Executive Order.
Vehicles without these required information labels are not legal for sale in California.

California Code of Regulations, title 13, section 2766(a) provides an exemption from the requirements of section 2755 for metal tanks, coextruded multilayer tanks, and structurally integrated nylon tanks on SORE equipment with engine displacement less than 80 cc. Section 2755 contains the permeation emissions performance standard for equipment that use engines with displacement less than or equal to 80 cc.
This exemption does not apply to any fuel tank for use on SORE equipment with engine displacement greater than 80 cc. Permeation emissions data or the Executive Order number of a certified fuel tank must be provided in certification applications for equipment using engines with displacement greater than 80 cc meeting the design standards of Cal.
