anyone fitted r1 fuel injected engine yet could do with wiring diagram if anyone has one should i use original fuel pump and how would it fit into tank ?

you can buy microfiche on cd from 'ficheman' on ebay i think they are about £10, covers all servicing/ repairs upto 2004. I have a one for my 'other toy' (158bhp @ rear wheel!)

You could possibly run a fuel pump from a fuel injected car with the pump mounted to the chassis i.e. xr3i, golf gti, astra gte? The R1 fuel pressure is 284kpa (2.84 kg/cm, 40.4psi) any of these should supply ample fuel for the R1 motor. Hope this helps
