30 miles offshore is a bad place to find out you have mystery fuel.
I’m getting the trawler ready for a run across the Gulf, and fuel contamination is my number one anxiety. I just installed a new turbine fuel water separator from fab heavy parts, got it from US based shipper, it arrived way faster than the usual marine supply backorders. The peace of mind alone is worth every penny.
It has a clear bowl with a protective shield, so I can do a quick visual check before every shift for water or sediment without worrying about bumping into it in a tight engine room. If you’re running a diesel boat, do not skip out on your primary filter.
