Offshoreonly.com - Water in fuel issue...Opinions?

OK, this will be a long one. We've had our current boat for a little over 4 and a half years. Great boat.....but I've had a issue with it since the day I got it and I simply just can't figure it out. I get water in my fuel tank...
Before I go on, I've owned boats since 1982 and have generally worked on them myself, with the exception of internal engine work. I've also researched the chit out of this subject. I know all of the things that are out there in GoogleLand about the causes and fixes, none of them worked. Replaced the O-Rings on the fuel fills, replaced the gasket on the fuel sender on top of the tank, made sure that there is a loop in the vent hoses, checked for leaks....none of them are the issue. I've had the water tested and it is fresh water. (Wanna know how to piss off the guys at the pool place?) :D There has NEVER been a drop of fuel in the bilge. The ONLY possibility that it can be is condensation....and, according to all of the experts on the internet, there is no such thing. It's impossible for it to happen!!!

The boat was a trade-in :rolleyes: and the guy who traded it in had just finished "re-doing" the whole boat. Maybe it was stored inside and they never knew of the issue? I don't know and really don't care. It's a used boat, it surveyed good and I bought it. I'm not one to blame chit on others, I just fix it...or try to. :D The first time that it happened was a few weeks after I got the boat. We left the dock and the boat cut out about 50 yards from our dock. A friend towed me back. I thought that I had gotten bad fuel. Called a guy, he came out and pumped the water out of the tank and showed me the plug at the back of the tank. (see picture) He told me to go buy some clear hose, a primer bulb and put a coat hanger in the bottom part of the hose (See picture, it's like a McGyver thing) :D

I've gotten into the habit of checking the fuel every time before going out... It takes 5 minutes to do, not a big deal, but it's a pain in the azz. The boat is stored on a lift, under a canopy and my lawn irrigation sprinklers do not spray water onto the boat when the are on. (Told ya that I've checked everything) LOL
I use my bulb and hose apparatus and get the water out, let it settle and then pour the fuel part back into the tank. I've got three pictures below of the last three times that I've pumped it out. All one week apart, it's pretty much the same amount of water each time. It hasn't rained in the last three weeks, so it's certainly not rain water getting in there!!
I've owned over a dozen boats through the years and been around boats of friends and have never seen this issue. There is definitely a problem, but WTF is it? One thing that I have noticed is that if I put gas station 10% ethanol fuel in it, it's a little more water, but I haven't done that in over a year. The three photos of the water/fuel in the clear plastic jug is all REC 90 fuel from a marina with new tanks.

Anyone seen this before? Why is it happening to this boat and no others????https://cimg6.ibsrv.net/gimg/www.off...c0849c8d55.jpg
