I have a Blue Print 302 ford engine in my cobra. Had a cooling system issue. I ordered the largest cooling system pressure testing kit. A couple dozen adaptors testing radiator caps came in the kit. None of those fit my FF supplied radiator cap requirements. Does anyone know where I could purchase a pressure testing cap for testing my cooling system.? Is there any type of nomenclature to help me locate the correct pressure testing cap.
Thank You
