I searched but came up with nothing. What is the fuel tank capacity of a 91 Civic si?

 

look in your owners manual... it tells you there... in my dx crx i have about 10 gallons... when the needle goes on the red i know i have 3 gallons left which i can estimate will give me roughly 80-90 miles b/4 i run outa gas

 

its a 12 gallon capacity in my 91 CRX Si, my fuel gauge dont work and i ran out of gas

 

Hope this is what your asking for And damn that came out big lol
