If you need to replace the gasket in your Bluefin, it's quite simple. See photos below. Simply peel out the old one and lay the new one in place. Start at the top deck of the part and place the gasket in the groove. Push down with your fingers to get it to stay in place. Using a tool like a combination wrench, push the gasket down into the groove to make sure it's seated in place. When you get to the top where you started, cut the gasket leaving about 1/4" overlap. Tuck the cut end against the other and seat the gasket again to remove all lumps and bubbles.
NOTE: the first time you clamp that part, it could be quite hard as the gasket is being set in place. After the first time, clamping will be easier.
