Hello together, I am “non-brand” but you can certainly help me. Do you have documents or a program (like also analog with measuring slide, if by chance just removed) with which you can determine the inner diameter of the following cooler hoses based on the part numbers? Number 1Number 2 Unfortunately, the dealers can not help me any more. Background: After a motor conversion I have to change my cooling water line. Since there was not the engine in my model there is also No form hose for this project. Now I’m looking for a narrow 180° tube with 12 inner diameter which I could “flick” to my line. It has to be form hose – standard meterware knocks off. Thanks to you for all the information, tips and ideas you can give me during my project.
