Hi guys - I have just acquired an RD07 Africa Twin and am replacing the oem fuel pump with a Facet 40105 from Aircraft Spruce in the USA. My problem is the two unions that should accompany the pump - I am told that I need 10mm ID unions whilst the website for this company lists everything in inches. :? Could anyone enlighten me as to the correct size for these items - Many thanks in anticipation!!
