My head was screaming 'dont take those injector clips off, you will drop them and lose them!' And 'why are you taking them off anyway?' The BMW hose clamps break off when you have reached the correct torque. Fkg great if you have to take them off again later. You can buy special 'fuel hose' clips but IMHO your bog standard 'jubilee clip' does a better job. I prefer to use a small socket rather than a screwdriver to tighten them up. Either way, great result!
