The best thing to do is to identify the part number. A good place to do this is here...

Make sure you get the part number for your year and engine. The year goes by (the last parts of) the VIN number.
Once you know the part number you can tap that in to any (or any good) Land Rover parts supplier's web site and they will often come back with a choice of different manufacturer's parts. The Genuine Land Rover parts are usually wickedly more expensive than 3rd party suppliers. An OEM product should be the same as the LR product just without the LR badge and (in my opinion) usually the best to go with. Then you have aftermarket suppliers - beware quality though - you make your own risk assessment on whether its right to save 50p, £5 or £50.
I have to say, there is often not much choice when it comes to hoses and pipes, so you may be stuck with a LR part - but even then its likely you'll get a lower price for LR parts from an independent supplier rather than a dealership.
By the way, good choice in Freelander - the L Series are awesome
