300tdi air filter hose

My 90 has a 300tdi retrofitted to it. The air filter housing is the original Defender 300tdi type. Since the wings are earlier type, the hose connecting the air filter to the wing has been omitted. i have recently fitted a mantec snorkel but have not connected it to the air filter yet. I have tried to purchase an original hose but did not find on the local market. So far I have managed to obtain the Y-piece including water trap. Can anyone give me hte part numbers of the hoses that connect the y-piece to the air filter housing and the y-piece to the wing? Or else, can anyone suggest what hoses to use and what reducers to use? The diamaters are different.

This help?

You're the man. Thanks a lot! They ain't exactly cheap Will have to bite the bullet

Search for something like 'defender air intake' on eBay, that has a few hits and you may get something second hand that will do the job. Alternativly ask in the sales/wants on here if you haven't already, you may be lucky
