My brother has just had the fuel lines replaced on his 4x4 saph Cosworth by the local garage, they used copper pipes for the job and the car now hunts really badly and seems to have lost power!!! We have been told by an engine builder that the cause of this could be that they have used the wrong diameter piping ( too big ),could this be the cause? If this is the cause we are just going to buy some braided fuel pipes from a recommended seller and re do it ourselves! Also could someone tell me the correct inner diameter of the pipes we should be using and does it all have to be the same size from the back to the front of the car??? I have tried search but nothing really of interest came up.

Thanks in advance

also the diamiter could be too small and i aint heard off copper pipes being used for fuel before either though i might be wrong

Yeah well the pipe that burst in the first place and caused all the bother was plastic and thats why we couldn't understand why they used copper?? But you know how it is they are never wrong lol
