Hi Tom,
Thank your for your reply, I have finally checked whether i can switch the pick up tube and finally the answer is no, my old pump have a smaller body with 4 bolts, where the pick up tube is so cant fit it on the new style pump that has a bigger body with about 6 bolts.
I will return it to top end just hope that they will exchange it as i already emailed them about it the day i received it.
otherwise i'll have to look for the more recent longer pick up tube if anyone has one?
Thanks
