Kumabaga 40 liters capacity ng fuel tank ko. At most 20 liters lang karga ko. Bigat din kasi additional 20 liters sir. Imagine mo may sakay ka na 20 pcs 1 liter coke. hehe.
rm molivar is right about the space for evaporation. and ur tank is more prone to corrosion kasi yun moisture always at the top. mostly ang metal ng inner tank ay raw steel, meaning no anti rust. your only anti rust protection is the fuel itself since it contains oil and additives againts rust.
