@IaM-Ray posted:Can you show me a sample again Danny I have worm gears on my fuel lines and I was thinking of changing them, how do you know what size to use On what hose is my question ? @DannyP
Throw a vernier caliper on them. I generally go with a clamp 1mm smaller than the hose ID i.e. the OD of my 9mm fuel line is 14mm, so I use a 13mm clamp. There's a bit of range in the clamps, so using a smaller one keeps nut/bolt separated when they're tight.
