Choosing and using this product

Match this spare to the Diablo tank hatch assembly before ordering. The tank, hatch lid and individual fittings perform different jobs, so identifying the original part is more reliable than selecting a replacement by appearance. Check the old component, the connection position and the dimensions listed below. Where a thread is specified, compare its nominal size with the hatch connection rather than measuring only the outside of the fitting.

Compare the gasket with the hatch lid and its seating surface, checking the shape and position before removing the old seal. A replacement gasket must sit correctly around the lid rather than being stretched or folded into place. Inspect the mating surfaces for distortion, cracks or trapped debris, since these can prevent an otherwise suitable gasket from sealing properly.

Before replacing a tank component, isolate the tank system and prepare the work area for the contents involved. Keep dirt, old sealing material and loose fragments out of the tank. Inspect the surrounding hatch and threads for damage; replacing one fitting will not correct a cracked lid or distorted sealing surface. Use the tank maker’s instructions for any sealant, fastening sequence and tightening requirements.

Once the part is installed, inspect the connection under the appropriate operating conditions before returning the tank to normal use. Check that connected hoses are supported and do not load the hatch fitting as the boat moves. Keep the part code with the tank information for future servicing. Select any additional hoses, clamps or sealing materials separately to match the installation and the liquid carried.
