Sorry that should of said do you know if the new pump needs timing up to suit ,as I ve been looking on the internet , some say it does and say it don't , The leak was from bottom , so I tried to reseal it but when I removed bottom plate tiny bit of metal filing dropped out , so put it back together and it doesn't run , so I am guessing pump is scrap , been looking for a cheap 2nd hand unit , but can only find a 2.0 ones the 2.2 ones go for silly money ,
