Looks like I'm going to have to rip out all my fuel lines and swap to SAE 30 R9.
Ever since I started the car for the first time and ran the petrol through the lines the garage has smelt petroly. Not like a fresh spill but just this back ground stink all the time. It leaks through into the house too which isn't pleasant. I thought first of all it was where I'd spilt some on the engine etc when I was changing over my injector seals but this is over three weeks now and the smell is just as strong. I can't find any leaks and have checked all hoses clips are tight. When you sniff around trying to find where it's coming from you can actually smell it through the hose. I wouldn't be surprised at this if it they'd been on for 10 years or something based on what I've read about modern fuel in R6 hose but this is only a year old (I assume).
I'm not so much worried about the extra expense, more the hassle of what was, with the engine and gearbox in, a painful job in the first place let alone with a face full of fuel on the cards
