The expansion tank (#3) is there if your car ever flips over and gas drains into the "expansion" tank. It's more of a safety tank than a true expansion tank.
Also, hose 6 was unattached and vented in my driver-side rear fender, which is a much better place for your gas to vent out to. You DO NOT want those fumes going back into your car. Before, most cars also had this venting into the rear fender.
If you haven't replaced all the hoses in a while, do so now. They get easily clogged. Imagine that going back into your car. Nope, vent into the fender. Happy Driving!! |
This is misleading.
Tank 3 is a wide spot in the line to allow the liquid fuel to separate from the air to have only fumes go to the charcoal filter.
Line 6 draws the fumes into the intake to burn them up.
This is a closed system.
