I also thought of a couple more questions. All of my senors came w/ my harness and I am not sure if it was a 5.0 or a 5.7. How can I tell if they will work the 5.7 ecm 1227747 AMUR? I am going to order some 3/8" aluminum tubing from summit for my return line. What is the best way to connect it to the rubber line and keep it from slipping?
