Hello Gareth,

The fuel lines are 5/16", so the metric size will be either marked as 7.9mm or 8mm.

People I've spoken to on the subject reckon the standard size is too small for high output engines. If you have ambbitions to up the power above 200hp then perhaps sticking with the 10mm would be a good idea?

Hi,
used 8mm microbore copper from the rear mounted facet pump on my weber 500 equipped car, linked up with 8mm inner diameter steel braid hose.
Regards,
Dave
