If it has a plastic cover on the engine, then it's a CF2. If it's a metal cover, then it's a CF1.
Having said that... brake pipes are mostly identical (some models have a marginally shorter front hose?) so I wouldn't over-worry.
The steel pipes, even if in good condition.. will be potentially rusted fast to the rubber hoses where they connect... so if you want to replace the rubber hoses, you also have to be ready to replace the metal hoses.
You may be able to separate the pipes with the usual.... Plus-Gas, WD40, Shock-Unlock, blow-torch, rabbit's foot, cloverleaf
or prayer... but be careful when you unscrew the nut that you don't twist the metal pipe and effectively block it by collapsing it.
Also use a proper brake pipe spanner (the 5-sided doodah) since it will grip the rusted nut on more surfaces so less chance of rounding it.
Once the work is done, get into the wheel arch with some silicone sealant (specialist auto stuff or even the white gunk the plumber uses around your bath) and seal where the metal pipe goes into its union ("male" end) and where the union screws into the rubber hose... to keep water/mud out and save them seizing up again any time soon.
