Can you give me a little more detail on how you modded the vent?
Hi Lou,
It has been about 10 years, so it is not totally clear; I will try and recap what I remember. There is a cap that floats on top of the vent. Even when the cap is in its lowest position, it should let air pass. I removed the vent, made sure it was clean, then I remember removing the cap and cutting some small notches in the top edge of the vent stack to be sure there was absolutely some air flow when the cap was in its lowest position. Then I snapped the cap back on. The result definitely allowed more air to pass.
The vent is plastic and is just lightly pressed into a hole in the carrier near the fill hole. Thoroughly clean around the vent before removing it so you don't get small rocks falling into the hole after you remove the vent. When putting the vent back, be sure it is fully seated.
