There are numbers inscribed on my new injectors and I assume these are the flow bench numbers but Im unsure how to read them. Can anyone shed some light on this topic for a bonehead like me?
Part number on the injector is D1151BA. These are the standard PTE 550s, I was just trying to figure out f the numbers were relevant since they didnt come with the promised flow sheet.
