Hi all! I bought some replacement coils yesterday here in town at my local shop and discovered today that the coils are to tall. When I put the new coil on the center post and then try to screw on the top of the tank the top can't screw on because the coil is sticking up to far. So I hopped online looking up pics/vids of this stuff and noticed that some folks use what looks like the coils minus the pointy part that sticks out through the hole on the plastic cap. At least it looks like that piece was missing in these pics/vids. Sorry I don't know the actual name for the pointy upper most piece of the coil. Would the coil function properly without that piece?
