Definitions ► Diurnal emissions - evaporative emissions that occur as a result of venting fuel tank vapors during daily temperature changes while the engine is not operating.

► Evaporative - fuel emissions that result from permeation of fuel through the fuel-system materials or from ventilation of the fuel system.

5

Definitions ► Pressure Relief System – A fuel system that provides means to momentarily release tank pressure and relieve vacuum within operating specifications.

► Spitback/Wellback – The occurrence of fuel spitting, splashing, or flowing out of the fill pipe during fuel fill or after nozzle shutoff.

► Primer bulb – the in-line device intended to pump fuel from the fuel tank to a connection point on an outboard engine to prime the fuel supply system for engine starting, usually by mechanical or manual efforts 6

2010 Version of H-24

3. The Environmental Protection Agency has promulgated regulations regarding the evaporative and diurnal emissions for gasoline spark ignition marine engines and fuel systems in 40 CFR chapter 1060. Refer to the CFR for complete, current federal requirements.

► ► ► ► ► 2010 Version of H-24 Canister Sizing Minimum canister size shall be calculated as follows : For Boats ≤ 26 ft the canister size in Liters = .04 x Fuel tank capacity in gallons.

EXAMPLE: A 18 foot boat with a 25 gallon tank would require a canister of .04 x 25 = 1.0 Liters

For Boats > 26 ft the canister size in Liters = .016 x Fuel tank capacity in gallons.

EXAMPLE: A 30 foot boat with a 250 gallon tank would require a canister of .016 x 250 = 4.0 Liters
