tank assembly cracked/leaking

Ordered a new tank assembly, but the new part also leaked because it had a hole in it. Ordered another that worked fine. Used a flat head screwdriver to remove the clips covering the screw holes to the tank assembly cover, then a phillips to remove the cover screws and the screws retaining the tank. Did not use the tubing that came with the new tank (removed it by taking out the neck clip then simultaneously pushing back on the neck piece while pulling out the hose). Used this same procedure to remove the old tank at both positions. Installed the new tank, replaced the clips, pressurized/tested the system and put the cover back on. Overall less than a 5 minute job...except for the extra week waiting for a good part.
