I would suggest you look in the C-75/85 or perhaps the C-150 manual for multiple line priming. This is not a problem just have your mechanic send in a "pro-forma" 337 form and then do it. They would accept it anyway but "pro- forma" they will issue authorization in advance.
Any competent practicing mechanic could try the following example. It will work. "Installed 1, 2, or 3; additional primer lines to cylinders X,Y,X all lines attached to common divider point and routed across top of engine to primer points." END
