Looking at swapping out my cp4 pump for a cp3, I've sourced a few pumps 0445010042 R70 which I believe is used on the older common rail engines, now I'm guessing I need the BMW pump for the ea288 engine without the pump gear on the back, can any clear these up that have done the conversion, I'll be making my own adapter as the price tag for these are ridiculous at the least
