Looking to replace all the nylon fuel lines on my 200.

does anyone know what internal diameter hose I need?

going to do leak off pipes on injectors,
lift pump pipes
fuel filter pipes
and any others I've missed?

TIA.

I think you will find they are thicker walled than 1mm.
1mm walled nylon pipe is a real bastard for kinking.
