Re: another tank cleaning issue
I can't argue with the wisdom of installing a good sized inspection port, it's the best way to go. On my own boat, while my engine was out I simply removed the tank and used a pressure washer and degreaser to clean the tank out. Simply stuck pressure washer wand in every orifice and rinsed till no more stuff washed out. No problems since reinstall and 20+ hours on newly rebuilt engine.
