The stainless ABA clamps that I sell are for 7mm fuel line only.  I am pretty
positive that they won't work with the 5mm braided line.  However I do sell
the stainless worm drive clamps that will clamp these smaller lines.  Because
the lines are not high pressure and because the braiding protects the rubber
of the lines it is safe to use the worm drive clamps on the 5mm low pressure
line (that is how the vans came stock).
The worm drive clamps are a good deal cheaper too.
