Hi advise please. Where is the best place to buy some replacement rubbers. I'm taking the tank out as I get the odd wiff of petrol so I'm going to replace all the Rubber pipes ,that are connect to the tank but I want the best quality ones as I don't want to do the job twice. Thanks in advance

The filler tank hose is the issue, you're fairly restricted there. Your best bet, this is what most people do, is to use wrapped silicon hose from a kit car supplier or similar. I bought mine from MSE performance, 200mm long (you don't need all of that) 55mm ID, I assume 4.5 wall thickness. MSE-performance as an ebay seller. Don't use EPDM.
The other fuel hoses, I.e breathers and fuel hose to engine, is a lot easier. All you need is to make sure that you're using SAE R9 rated fuel hose- the other stuff is rubbish. TBH, even R9 isn't amazing with modern fuels, but it's the best you're going to get.
I go size-on size with hoses over 10mm ID, under that I usually knock off 0.5mm or 1mm on the ID since the fuel clamps you're using won't create an even compression- so having the hose a little tighter helps. This isn't backed up by standards but I've found that sometimes size on size weeps a bit. Depends on the surface finish of the spigot and how good the clamps are- hose clamps, despite being better than jubilee clips, create very uneven compression, especially on small diameters. Ear clamps are much better for compression but non-removable and require a special tool.
