I have a leak

[Bushwacker]

Good job of tracking down that leak Dixon! Not sure of what sort of access you have on MA baitwell, but if the tube is brass, they're pretty soft and usually pretty corroded by the time they start leaking. If you can get a cold chisel or screwdriver on edge of flare, you can usually push tube in enough to get some needle nose pliers on it. Then you can just twist it enough to reduce diameter, and should be able to pull it right out.

For flaring tool, I've used 1/2" threaded rod with nuts, washers and a tapered 1/2" drive socket to get the flare started. Then you can finish with a ball peen hammer. Maybe not as pretty as a flaring tool but it get's the job done. Just be sure to bed it with lots of 5200! Denny
