I have collected some hose clamps and fuel hoses by now (yes, true rated fuel hoses), and have some questions, let me try the bare minimum here:
is there a rule that a larger wall thickness of fuel hose will require a larger band thickness of a hose clamp?
for example, in the original configuration from the factory, a fuel filler hose has a 4 mm wall thickness, and the matching hose clamp is 12 mm. BTW the clamp is a solid band of metal, not like the hose clamps from home depot with the holes in them and doesn’t have a slight curve on the edges. the fuel filler neck is no longer available new. The best substitute fuel filler hose has a 6 mm wall thickness. there are a number of hose clamps I have collected, but my lousy intuition says the one with the larger band thickness is the best choice for this.
I’ll post some of the relevant hose clamps if necessary.
