more durable vent hose for valvel cover?

[colin86325]

My vent hose (#10 in diagram below) seems to last about 2-3 years before cracks appear in it and it seems that this is a pattern.  I guess whatever vapors the hose contains cause the rubber to fail.  I've used BMW hose and after market hose and they both eventually fail.

Does anyone know as more durable hose that can be used? Like silicone hose? Does anybody have the hose size? Has this happened to anyone else?

I used silicon hoses which comes in different color and dimensions from a company. They also sell a m42 kit but now I can't remember the company name. If you look into my project thread, I have it listed there. I know Desktop Dave also uses them and he can tell you their name. I believe it is Hi-Performance or something like that.
