So, I have my tank dropped and my old sending unit removed. I have an SVT Focus pump assembly here, waiting to be dropped in. Is there a write-up anywhere on what to do to swap these in? The buckets on these are different from eachother, and the pump on my Mustang has a little black plastic tube coming off of the pump itself, while the SVT one does not. Anyone have any experience with this swap? Also, I have read about people drilling the buckets for more flow. Should this be something for me to consider? I'm naturally aspirated, and probably will be for quite a while.
