While i have the fuel tank out, i started trying to get all the loose rust off and converted/covered. The no.3 emmision pipe has extensive rust on the outside, doesn't look to difficult to bend a new one if needed.My question regards its interaction with the charcoal canister. In my searching it looks lime this hooks up directly to it.But the PO desmogged this 2f and there is no can to be found. Does that make this part obsolete. Or should i fnd an aftermarket one to put in the non existant cans place?
