Fuel Line Replacement

[White S3]

Hi All,
Some will have seen my FB post about my fuel line failure (thankfully while it was SORN in the garage). I have purchased a length of marine ethanol resistant pipe as per one of the recommended posts to replace the failed section BUT does anyone have any photos and details of which other parts of the fuel line to the engine and also the return line back to the tank than also needs replacement?
Do the injector O rings also need changing???
Any advice grateful received as I have 2weeks to turn it around before MoT!
Thanks

I expect you'll have a low pressure line from the tank to the pump, then a high pressure line to the filter and on to the engine, then another line returning from the pressure regulator to the tank. If any of them need replacing then imo it makes sense to replace them all.

I've never seen an injector 'O' ring seal damaged by ethanol and I assume they're made of viton or similar material which tolerates all the common fuel types.
