CVF Racing water pump?

Cool trickster! 've tried similar tactics, string,ect, a tape measure won't do it... think they're metric #s.. The best they can do is a white air compressor type belt... I'm doing the pulleys from CVF. Sucks they went up. But everything has, and will, continue to increase
I know I went to an AutoZone and they just had this measuring tool that they stretch the belt over then pull it tight and it gave a reading of what size the belt was.. but I think somewhere encrypted in there is the actual length of the belt....
