*by K***L on 14 October 2022*

Good size and value for the $$ spent. It did leak fuel at flange where line ties in. I tightened the 4 Phillips screws ( they were very loose) and almost it good for now. Their QA inspection should have caught this issue. Taking it on the water this weekend....should be ok.
