I need to replace some fuel lines (from the injector control to the injector) on my 93 VW Cabriolet. The site that sells the lines has 2 options for the 'Injector Size': M10 x 1.00 or M12 x 1.5.
I'm not sure what either of these mean or how I can check to see which one my injectors are.
Can anyone point me in the right direction? Thanks!
