Thread: fuel line replacement - sizes ?

hey guys, so i need to replace the fuel line (section from sedimenter to pump), and maybe also the return line. Is it just a case of getting the correct size from a hydraulics specialist or are there dedicated landrover fuel lines ? sorry if this has been answered somewhere else, i've done a lot of searching thus far.
is it 3/8 fuel line
and 5/16ths RETURN line ?
cheers

Fuel line from Repco, Bursons etc will be fine. I would say 3/8 would be enough.
