ok just replaced a motor and it was half a dozen people doing it so it was a mess

#1 on the starter there is 2 wire on the big screw one from battery and one from alt and one on the little one a purple wire is that correct

#2 can u replace a ring in the side of the fuel rail with just a normal o ring or does it have to be a specific one its on the pressure side not the return side

#3 im going to attach a picture and there is a plug with red on it i dont know what is can someone identify it for me
ok i dont know how to attach a pic but its on the alt side
