I had hoped to use high quality Teflon/stainless fuel lines on my build but despite being way over specified it is not allowed due to lack of markings.
Has anyone used it/found a supply of correctly marked hose or am I doomed to use rubber (which I dislike a lot!).

Use R9 rubber hose then swap to your preferences post IVA.

Obvious when you think about it! Thanks.

Hi,

I've used 8mm copper pipe that I also gave to some friends previously who passed SVA without issues, so am keeping my fingers crossed that this also isn't something that has changed and I've missed.
