I've had a Bosch 044 external fuel pump fitted only a month ago and as of last night, it makes a loud whining noise continually. I had similar issues with the previous Bosch VL turbo pump that was installed but only in extremely hot weather. Fuel is never lower than 1/4 full in the tank so that shouldn't be the cause. Could there be a blockage somewhere or do I just have a faulty pump. Any help would be great.
Thanks.
