hello everyone i have a quick question about the 7mgte oil pump, is the pump the same for all 7mgte engines and years or it there a change at some point. i have a 7m pump in front of me now its an oem pump. has two "toyota" stamps on it along with "AISIN" stamped on it in two places. i havent read about any oil pump changes for the 7m but i just wanna be sure it can be used on all 7mgte years. thanks for your help
