I have a couple of injectors that I need flow rates for. I have looked around and have found nothing. Maybe the people on the list could help. Here are the numbers: Bosch 0 280 150 209 Bosch 0 280 150 902 Siemens 4418474 With this, what is the formula to get sec/gram from #/hr or grams/sec. I haven't messed with this stuff that much.
