Fuel test port cap is what you need, (low side, blue) A/C cap may work. Newer A/C caps (R134) are larger and will not fit. The older (R12) black (may be blue) caps is what you would look for.
If you can find a evap. system test cap (green and on most late model gas cars and trucks) I think it may work best for you because it's fuel rated.
Most auto parts stores should have these. HTH
