NMMA Testing
All testing conducted in 2005
Overview
- PERKO-Delphi Marine Canisters were added to 14 various size boats to determine if the addition of a carbon canister would create any issues.
- The canisters were on the boats for one summer testing season.
- The EPA requirement is for the canister to have an efficiency of 50%. (capture 50% of the hydrocarbon going into the canister)

Typical Installation of Canister for Testing
The canister was protected from fuel slosh and from water splash. NOTE: This alone will not be a production solution. A 5% vapor space must be maintained in fuel tank to allow for thermal expansion of the fuel.
Inverted loop prevents water from entering the canister
Fuel vapor separator prevents liquid fuel from entering the canister
