Like that, but S rather than L.
Sure, like that, but for the SDU, as the original poster clearly asked:
Are there any aftermarket reverse pumps like the LDU ones for SDU haven't found any.
There was no need to tell someone who said he was aware of the LDU reverse pump and needs an SDU pump instead that there is an LDU reverse pump. I suggest that you try reading the post to which you are responding.I was asking if he was looking for a similar unit. There was no need for your salty remark.
