Fuel Tank capacity

[aminga]

I know the capacity of the tank is supposed to be 18 gallons but what's the most you've ever filled up with. Cause I put 20 gallons in yesterday and I don't think it will hold that much.

Your gauge is off or tank was extremely low.

There's an air reserve on all gas tanks Al. It's there for safety in the event of a crash. It's usually about 4 or 5 gallons.
