Question on the Vapor Canister -

[Willis76]

couple of questions -

What is the purpose of the vapor canister?

Do these ever need to be replaced?

If so, how would you know when?

Is there any routine maint required?

Was always curious why it was there - thanks

Collect gas fumes from the fuel system when off for later consumption via a line to the carb. There is a filter that is supposed to be changed. I have the filter but can't figure out how to get to it.

You replace it when it starts sucking vacuum (?) at idle. To remove it, the panel below it comes out, though not willingly--yep, it's a Corvette.

Thank you both

Thanks - I see that my old stand by Doc Rebuild has a pretty good description of the hoses, etc. I will need to trace mine to see if all is still there and connected.

Thanks again -
