Mine came with a regulator, pick up filter, orings and new wires. Yes I had to disassemble the fuel pump sending unit to install the individual components not sure how yours differs. Here is what mine came with.
Mine started my just cutting out a WOT while in Montana. Would just fall on it's face, cycle the key it would cure it for 10-15 min then it would return. The longer it ran the less effective cycleing the key(or pump) became. On the open road it got to the point that it would not rev above 5k, then 4k, before I knew it had trouble keeping the bike at 70mph on the freeway.
Fought it for two in BFE. Overnighted a pump to a hotel in Idaho. We took it apart in the hotel parking lot with some cold drinks and knock it out in less than a hour with tools we carried with us. All has bee well since.
