According to this you have a cartridge BB. If so since the chainset is FSA I would expect two possibilities, JIS square tapered or ISIS. You can look at where the bb spindle entering the crank arm per pic below to see whether you can spot the flats if it has square tapers, or measure the bb spindle diameter there - ISIS has 21mm diameter spindles, square tapered is quite a bit and obviously smaller.

From knowing the type you might be able to find out what spindle length is required by searching for documentation online. However the only sure way is to pull the cranks and measure it.
