I thought it was the other way around for pumps. Hence the low flow, high pressure fuel pump feeding the DI system while the high flow, low pressure pump feeds the port injectors and the high pressure pump. Make sure the high pressure line has plenty of supply via a low pressure, high flow pump.
But I'm sticking NA for now. You're the one with a problem to solve and money to make.  |
Not quite, the low pressure fuel pump (55 psi) in your gas tank feeds both the port fuel injector rail and is also the fuel supply for the high pressure DI pump which is camshaft driven and runs at pressures north of 2500 psi.
