I have a small issue I think. I believe I have some water in the bottom of my main tanks. Reason I say this is my boat is equipped with a diesel heater which I never really got to work. I pulled it out last year and rebuilt it but still it does not function properly. Played with it for the last couple of days and noticed lots of water in the line therefor giving me a no start fault. Primed the lines until all was clear and then she fired up and ran like a champ for a few hours before I shut her off. Last night I decided to try her out, she started up fine but a few minutes later she conked out and once again a no start fault.

The filter is transparent so I can see there is once again water in there. My Racor main engine filters hardly see any water by the end of the year, in fact I just emptied them yesterday, maybe 1/4 ounce total for both.

Theory, my heater draws from a very small 2mm ID diameter copper fuel line inserted from the top of my starboard tank. I am thinking this tube is inserted almost to the bottom and therefor can suck up water in the tank. I am going to try to loosen the retaining nut and pull up the intake a couple inches to see if it solves my heater water problem however this would indicate I do have a little water in the tank/s

Question, is this normal to have a little in there or should I be looking at getting this out of the tanks. If so, how is this done?
