Alan, Sorry for the lateness, but I would ask Chris Prince. In my case, a TA21, I keep a reconditioned spare in order to fix a problem quickly and then send the other away to a pump specialist. In the past it has come back with the latest innovations. That pump has now given 5 years of trouble free motoring. Richard Melbourne Posted by RichardWallach 07/11/2015 21:39:37
