Snorkel fitting advice.

Hi

I will be fitting a Safari snorkel to my 200tdi Disco this week.
Does anyone have any tips or advice for fitting one of these ? Any problems I can expect to encounter ?

Also is the air filter to turbo connecting pipe watertight anyway or do I need to do anything else to it ?
Anything else to think about sealing/waterproofing ready for wading ?

Thanks

axle/box breathers?

Already got those extended into a manifold in the engine bay, just need to run the 8mm pipe up the snorkel. Is this easy enough to do ?

check air box thres usually a rubber valve that needs siliconing up

didnt you get instructions with it?

I did, but really after finding out if there are any common problems that regularly come up while installing these.

Whats the best way to get the breather pipes up the snorkel ?

Thanks
