What is this Part?

[71SandbugCharger]

1971 Charger with 440. What is this part, it looks like a black painted soup can with two connection prongs. It’s mounted under the battery tray on the driver side and doesn’t seem to be connected to anything.

My son’s car.

Thanks!

Vapor Canister?

That is a Vacuum storage tank. 66-70 also used them on AC cars. Was it an A/C car originally? Maybe the strato-vent cars had that also.

Looks like the vaccum canister on vaccum operated headlights cars 68-69 Chargers and 70 Superbirds. I know 71 cars didn't have that so-----?

Did a '71 charger have an "air grabber" hood door?

 

[71SandbugCharger]

It was an AC car. Definitely a 1971.

I thought the small canister on the firewall was for air grabber cars, 70-72.

That A/C is why it is there.

71 cars had hideaway headlites as an option

And 71 hideaway headlights are electric.

The only 1970 Chrysler corporation car with vacuum headlight doors are Superbirds. All the others went to electric.

As stated above, vacuum reservoir. My '71 A/C car has it as well, although mine is still hooked up. Service manual shows it in the diagrams for vacuum routing for the heater box.

Also as an FYI, there's an inlet and outlet (check valve). If you hook it up backwards, you won't have vacuum to operate your heater box doors... I spent a lot of time figuring out the previous owners screw-up on that one.
