Hi Mark,

It is the fuel line that runs from the fuel shut off valve along the side of the fuel tank to the first filter.

Thanks

Mark,

Can you be more specific on which copper fuel line you are talking about?  If so, let me know I will try to take a measurement for you.

Could someone please tell me the external diameter of the copper fuel line. It will obviously be the same as the ID of the fuel hoses.

I just can't remember it.

Many thanks
