Overf here I ask for fuel tubing ans they sell it to me by the 1m length. All they asked me was what diameter and I said 3mm and he said " yup, got that in stock."<div>Tygon is around $8 / metre, the Stihl Viton tubing (actually just a generic automotove ViTON tube) is $5/metre.</div><div>I could probably get it cheaper if I could find a scooter mechanic who carries that diameter but most start at 3.5mm</div>
