Arrived quickly
Tank arrived quickly and fits as it should. The pictures showed a cap being included, but it was not. In all fairness, at the bottom of the specs it said it was not. My fault for not reading everything. I was more interested in getting the correct fit. I had to buy the cap locally to finish the job. Still a good value.
