Good to see you again TelePlayer.
Even the dealer mechanics didn't know the correct answer to this question when I set out to replace the pump on my '92 SSE supercharged a week ago. One of them told me that it causes the ECM to boost the idle under load, but I didn't believe that.
When you lookup the part to buy a replacement pump, it'* listed as "EVO" but not even the dealer knew what that means...
