Hi, I have just upgraded my track car to a Focus RS MK1, used to have an S2 turbo. I am looking to put my Small alloy tank and swirl pot in the boot, I know the Focus has an internal fuel pump. Can anyone tell me the fuel pressure that a MK1 RS engines require? Is there any preference to what type of external pump I use?

My car is running around 260-280BHP

I have a brand new Cosworth pump that puts out 6.5bar, would that be alright to use?

Thanks for all your replies in advance
