as above...what are the symptoms for failure? Its been suggested to me that this might be causing my engine stutter.

When my car has warmed up the car can stutter on throttle. you can see from the fuel pressure gauge that pressure drops to zero. back off the throttle slightly and you can watch the pressure climb and then its ok until the next stutter!

when this happens the fuel pump also gets very noisy

thought it was fucked but i put on a new GpA badboy yest and its still the same!
