With Dave Manning's direction and assistance, we checked the fuel tanks for leaks. I had completed them two years ago, so the ProSeal was sufficiently cured. One balloon was inserted into another balloon and then placed over the fuel tank fitting. After lowering the pressure on the air compressor to about 30 psi, about eight ounces of pressure were pumped into the tank. The left tank tested ok, except for around the gasket on the fuel sending unit. The gaskets on both tanks have dry-rot. The right tank tested ok, with no leaks.
