For the original question about water getting in your fuel. You said the DuBro jug system might not be sealing well enough. Usually they have an o-ring on the probe that has to be in good shape. When you store your jug and it gets cold at night or the next week, do the sides of the jug tend to suck in a bit? If so it is sealing very well. I use the Sullivan (or is it Slimline?) cap and probe system with a tiny o-ring and it seals remarkably well. An extra o-ring came with it but after about 5 years it is still sealing well. If there is a small amount of fuel in the jug it works great the following summer.
The fuel line changes color, but doesn't get soft and mooshy, no. I use Dubro Medium blue tubing, I get a 50ft spool every other year or so. I have the Dubro system in use and it works fine. I had sealing problems between the cap and the jug. Needed to cut a new gasket for the cap. I o-ringed the in/out fittings for the fuel pump but until I changed the jug gasket under the cap I did re-cap the jug at the end of the day as a precaution.
