suppliers of underbonnet (hood) vacuum connectors

[Gerard]

Hi,

I would like to replace a lot of my old vacuum tubing around the engine, but I'm having difficulty in locating the correct rubber connector pieces. My local parts places supply rather coarse and inflexible rubber tubing and I tried this already but its ugly and, doesnt seem to fit snugly and cracks easily.
I can get the nylon tubing no problem. If anyone can suggest the supplier or website of these little connectors,grommets and wotsits in the UK, Europe or USA, I'd be very happy.

Thank you

Gerard
