I want to run copper fuel line.... i had a petcock and fittings and small length of tube. It looks to be 4-5mm (1/8 maybe), is that ok? If not what size do i need?

The reason no one has replied is, speaking for my self I don't know how much fuel your engine will require. I do know that the 90* will slow down flow a bit. The China Girls all use 1/4" i.d., hope this helps.

Looks like a 98 villers. 1/8 ID. should be fine. I just happen to use 1/4" OD. tubing as it is easily availble.

I'm just guessing, Harry, but I think Russell is right. That motor can't use up gas any faster than it would drain out onto the ground if the petcock were open and the line going nowhere. You can always change it later if you're of a mind to.
