Pulled plenum for new coils and plugs wires today. Bad miss since last autocross. Discovered two corroded terminals and carbon tracks. Anyhoo tested fuel pressure and all OK. Pulled fuel pump assembly because I wanted to see its condition since purchased 5 years ago. All looks great like previous owner replaced it soon before I bought it. Hoses pliable with the black plastic oem squeeze clamps. I pulled it all apart to check plastic Y closely and to install proper metal fuel injection clamps. After reassembly I noticed that the pumps are a bit different. The one with yellow terminal also has two raised metal lugs. Note it in secondary position. The primary position pump terminal is body ivory with the metal lugs flush with plastic. Like a dumb bunny I did not take a pic before I disassembled it. So is yellow termal pump OEM as secondary or primary?
