Stainless steel parts are used. 13. Vapor control valve- Controls vapor flow to charcoal canister 14. Filler tube- Improved coating is applied and anti-siphon screens installed. 15. Fuel filter- Material changes are made for "alcohol fuel compatibility." 16. Charcoal canister tray- Protective enclosure. 17. Evaporative emission system- Charcoal canister system enlarged and modified for additional alcohol fuel vapor capacity and higher vapor flow. 18. Vapor (rollover) valves- Helps to increase fuel capacity and vapor flow. Material changes are made for "alcohol fuel compatibility." 19. Fuel tank- A specially coated steel fuel tank is used for "alcohol fuel compatibility." "Alcohol fuel compatibility" means that the component performs satisfactorily, is durable and does not contaminate the fuel when tested in 13
