Thin vs thick fuel line hose spring clips?

[Purplestar]

Which is a better secure for the fuel line hose that is attached into the petcock? The thin ones or thicker ones?

I don't know if 1 is better than the other but I prefer the wider ones. IMO it spreads the clamping area over a larger area and won't cut into the hose like the wire one will

I would recommend using the 5/16" Tygon fuel line.
It is expensive, but it's some of the best low pressure fuel line for our carbureted bikes.

Probably as much as anything, the condition of the fuel line determines how well it attaches and seals. A new(er) pliable hose will seal with minimal effort.
