Fitment and tank venting
The tank must have a separate functioning vent. Thermal relief does not replace normal tank venting. Verify the filler-neck dimensions and exact thread before ordering. A nominal 2-inch connection does not establish compatibility with a 2-inch NPT fitting. ACE lists this cap for aluminum diesel tanks in reefer trailer and International medium-duty truck applications. For generator tanks, confirm the filler neck and vent arrangement before selecting this cap.
