AU Injector Size and Fuel Reg KPA I6

**Sorted** · 17-08-2009, 05:17 PM

Searching Google I have found that the part number for the AU Injectors is:-

Bosch 0280 155 844

And they Flow 20lbs/hr

They also have 4 pin hole which spray the fuel

Also i read somewhere else that the Bosch 0280 155 844 flow 14.3lbs/hr

And I have no idea what the Fuel Regs for the AU's are rated at - can anyone help me out?

Is there a difference between the XR Models and the Std I6 models?

Sweet - thanks for that

SO whats the flow of the XR's Injectors - I assume they have more flow than the Std I6

Pretty sure they are the same,they have a slightly larger flowing fuel pump though
