Passenger side is coolant tempature sensor it controls idle advance, top of block by #2 is for the temp gauge and the other is for the temp light, as for plastic was it black? if so it was the o-ring stuff? if not

it was black and my next question is should this line be replaced or will it be fine and seal ok?

If it is the steel line it will be ok you just need the seals, I think they came with the IP install kit?

If it was the rubber gasket on the IP fuel return or supply line, you should replace it. You can make your own from fuel injection rated 5/16" fuel hose, or you can get the right one at IH.
