Blue spring upgrade question

Was changing out t-stat after thorough flushing ..decided to do blue spring upgrade..however the kit comes with 3 o rings..1 green..1 yellow.1 black..i know the green and yellow go on fuel line adapter..however the third black one is a mystery..watched youtube and every upgrade is on a newer model with no seat..i have an early 03.. so plunger and seat must be replaced..does anyone know where the black o ring goes?? Behind the seat?? Not sure..thanks in advance

There is no fuel pressure pids on Torque or Forscan. You have to buy a cap, as you did or you can use the port on the housing. You would need an adapter to tie in to the housing port. Then you can use an electric or manual guage to monitor pressure.
