This is a set of Kent-Moore J-36088-1A (blue) and J-36088-2A (red) fuel line quick disconnect tools for 5/16″ fuel lines (red) and 3/8″ fuel lines (blue). I marked these as used, because I don’t know, but these are in great original condition, as the pictures show. I inherited a batch of vintage Kent-Moore GM special tools so will be listing all of them for sale.
