I recently put the Walbro pump in my car while I had the rear and exhaust out. The pump is a little louder than stock so I don't know if the problem existed before replacement or not. The problem is when I shut the car off the pump continues to run. Sometimes as long as 2 minutes. So far it has always cut off on its own. What's the deal with it.

Perhaps its the oil pressure switch. Try unplugging it and see what happens.
