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.

6
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

2010 Version of H-24Canister 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 gt 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
