Fuel Expansion tank?

[iansane]

What does it do? Is there a good way of re-routing the hoses from it? Possible to delete?

Gasoline has pretty high vapor pressure. VP is dependent on the temperature. The volume (vapor) inside your gas tank will expand/contract with the rise and fall of outside temp. The vapor needs to have some place to go and that is what the expansion tank is for. I would leave it alone. Where would you re-route it to?

Thank you for the info. Sounds like a needlessly complex system.

The expansion tank itself isn't a huge deal but I'm trying to move/delete the weird metal tube that runs through the passenger compartment.

I got rid of the charcoal cannister, evap valve, and engine compartment hoses but left the expansion tank and vent hose that I coiled a couple times and added a cheap mini gauze filter on the end. This is hidden under the plastic shield.

I had no need for an evap system on my engine.
