Looking to replace mine and read that they can be replaced with a GM part, but never could find what part. My research leads me to Bosch EV6/EV14 52lb/550cc Fuel Injectors, 0280158117 (Choose QTY) But my research is flawed in the fact that I have no idea what i am doing. Also fuel pump is another thing i'd like to replace. Searching a forum that is full to the brim of many areas of information is rough. I found some stuff, but then I find counter information to that stuff. Either way, I need to find a throttle body adapter as well, so off to continue the hunt!
