I actually wired the pump bacxkwards the first time and ended up having to drop[ the tank a second time to switch the wires, that was me being an idiot though
Are you sure your an idiot?
the second gens wiring is backwards, many have made that same mistake when going to the focus pump.
Rather than dropping the tank, he just cut and swapped the wires outside the tank in the wiring harness.. worked like a charm
