To find the fuel tank capacity for a specific 1965 car, you'll need to specify the make and model. Then you can consult:
* The owner's manual: This is the most reliable source.
* Online resources: Websites like Edmunds, Kelley Blue Book, or car-specific forums might have the information.
* A repair manual: These manuals often include specifications like fuel tank capacity.
Without knowing the specific 1965 car, I cannot answer your question.
