Should we replace our fuel in our new-to-us boat?
I'm wondering if we should drain and replace the diesel fuel in our, which we just purchased. During the survey at the end of December, I noticed that the 20 gallon fuel tank on the boat was about 5/8 full. The boat is winterized and on the hard (in the northeast), but we ran it for the survey and re-winterized it. I would have prefered that the tank be nearly full for the winter, but we didn't own the boat then, so no choice.
The fuel tank is only about 3-4 years old, which is great, so it doesn't have 25 years worth of crud in it. The Racor fuel filter bowl looks very clean, and continued to look good while we ran the engine for about 30 minutes at survey. We'll also be doing a sea trial in the spring before we make the trip home to the Chesapeake. I'll also be replacing the fuel filter, and bringing several spares.
All that said, the fuel in the tank is probably at least a year old--the boat didn't see much use last year, and of course it's 5/8 full which means potential condensation and growth (at least theoretically).
So my question is, do we need to drain the tank and refill with fresh fuel before spring? Is there a big risk of water and/or growth in the tank now?
Please let me know what you think.
