Dan,
I decided that my pump was suspect and luckily managed to pick up a good second hand one off ebay for around 175 bucks
I fitted it and it is much quieter and doesn't run as much, now I can't hear it from inside the cabin. :D
Mind you the mounting bushes seemed a bit shot and it was touching the body, so that would have made it more noisy.
Eventually i will probably replace it, but for now it is better than it was for sure, charges in around 20 secs from first start.
Steve
