Do you know what's required to make a custom silcone hose?? If so you will know that a bespoke pattern has to be made for the hoses that are needed and if its a one off then it will end up in the bin afterwards, problem being the cost to make that pattern far outweighs what the actual hose is worth.. If you want to proceed then pm me and I will provide you with info for a company that can and will be able to sort this.
