van line plastic bubble on pssgr side???

[wazazzle]

Does anyone know what the vac line and that plastic bubble goes to under the passanger fender? Mine had a huge crack basically splitting it in half from what looks like a prior owner accident. I removed the bubble and have drove on it the past few days.. is this going to hurt me? What is it?

That is a vacuum canister. Stores vacuum for HVAC and possily brakes?
They sell aux. canisters for the brake booster when you run a radical cam to keep your power brakes.

Nope, just HVAC. The three-way check valve prevents air from flowing in the direction of the booster.

It's reserve vacuum for when you go to WOT.
