Internal combustion engines can use a variety of fuels, the fuels available at US competitions are gasoline of octane ratings 93 and 100, and E85. No fuel additives can be used.
Chemistry
Gasoline is typically approached as pure octane. (Do we need to cover the actual reaction here?) This is what yields the stoichiometric ratio of 14.7 grams of air per gram of fuel.

Injectors
Throttle Body Injection
basically electornic carb
Port Fuel Injection
Fuel Injected into the ports just before entering the combustion chamber. Usually leads to well mixed charge [citation needed]
Direct Fuel Injection

Fuel Storage
Tank
volume mounting material form factor (exterior and interior) sloshing is a meme
Bladder
just pour the gas in a kroger bag and let it flop in the wind /s
