What are the advantages of aluminum fuel tanks?

The main advantages of an aluminium fuel tank are that it's less susceptible to corrosion and is significantly lighter than other options, making it more fuel efficient. An aluminium fuel tank can last the entire lifespan of a vehicle if it is properly maintained, also making it cost efficient.

The lighter weight of the aluminium fuel tank also reduces fuel consumption and greenhouse gas emissions, which helps cover the extra cost of the aluminum tank and helps the environment in the long run. As long as the aluminium tank is at least one-eighth of an inch thick, corrosion should not be an issue.
