Hi

Has any of you ever replaced the black semi-rigid F Inj pipes- if so what is suitable for replacing them with

Is rubber high press hose any good for this or will it affect the running of the motor?

cheers colin

If you mean the short tails on the injectors as in early bosch then it is just standard fuel pipe.I just replaced mine with some 8mm 12 bar rated pipe and retained it with crimp on O clips.

yea thats the ones, it is the early ones (1987 v6)did it make any difference to the performance/running?

No it wont make any difference at all, its just a peice of pipe, just make sure that it is securely fixed.
