Die test kit in spray cans. One red Penetrate dye and one Developer white power. Any dry solvent cleaner will work, like acetone or MEK. Each can should be about $6. A compleate kit ($72) has 2 cans each of penetrate, developer and cleaner. Way too much for a single sailboat, unless you check a lot. Most common brand name is Crown - Fault Finder

Preheat the parts to about 100 - 120º with a propane torch before spraying the red dye. The dye seeps into the cracks as it cools.

DON'T get the dye on your gelcoat!!!!! You should get instructions with the kit. If not ask, the salesperson.

BTW. The threads on the couplers may give you a faulse reading, so maybe the spray cleaner would be recommended for that area.
