Thanks, I'll give that a shot if it looks like it's a problem. I installed two new Racor
500 filters when we bought the boat, so I'm not too concerned about the fuel any more. It sounds like two year old fuel should be okay. I also dumped six gallons of fresh diesel
in there about three months ago. The tanks
are clean. I wasn't sure about evaporative issues but after asking here it seems that's not really a problem.
