Brake and fuel line sizes

Seems as it looks like we’ll all get locked at home for a few weeks, it’ll be a good time to move forward with my car a bit.

what size lines should I go for? Brake and fuel. 3/16th brake, 5/16th fuel?

Seems good to me. I was going to go 10mm for fuel feed and 8mm for return (5/16”) but when I checked what the car manufacturers were installing as stock it seems 8mm is more than enough for what our motors make. I used aluminium hardline coupled with AN6 JIC fittings. Quite easy stuff to work with.
