Received the parts, opened them and placed the foam in the air cleaner box, then snapped the cleaner cap in place. They fit exactly and that is real good for a 31 year old Toro. They were genuine parts. Thanks for being here when I needed them.

Removed fuel tank and fuel line to to replace the fuel filter. The air filter was simply replace the old with the new foam air filter.
The problem with the repair was replacing the fuel lines. The Toro fuel lines were the right diameter but the orifice was too small and it did not allow adequate fuel flow to the carburetor. Toro ac knowledged the problem with some of their fuel line replacements.
