my boyfriend is doing a head gasket replacement on my '88 supra 7mgte. he is almost finished, but has run into one problem. On the charcoal canister, he is not sure where the one line hooks up to. he's figured out the vaccuum lines at the top of the canister, but at the bottom, there is a small hose which is attached to a metal line. where does this metal line get attached to? any help would be appreciated!:icon_razz
