mss is quite right. i have just replaced my pump. it was squealing like a pig. its the third replacement having used used parts . this time i bought a recon. £135 delivered . i have another now in stock for if and when i need it. the problem is you dont know the history or milage on a used pump. i had to go in there again to change the alternator for a new one as that was whining too , but i could not hear it due to the noise from the old pump. thats twice now inside a week. its not a bad job but it is work intensive, so i think what you paid was pretty reasonable upon reflection. 4 or 5 years ago these recon pumps were on ebay at around £70. not an exchange either. most sellers in every industry are upping prices trying to claw back pandemic losses , and there is only going to be one person footing the bill. ... your truly.
