There should be two lines from your "pitot" tube. One is for ram air, one for static air. Look around the circumference of the tube and you'll see holes. That's your static source. Many Ercoupe owners use static from the cockpit, but check and see that there are no leaks anywhere. A good way (probably not recommended) is to disconnect the pitot, then static at the panel and tube, then gently blow some cigar smoke, checking for leaks in the wings and the belly, finally up to the panel. You can also stick a golf tee in one end, and try to blow (not with compressed air) some air through. If you can, you've got a leak. If you can't then the line is sound, but check for kinks. A common place that they are loose is under the wing strip. Usually a clamp loosens, so check that point carefully.
