Anybody has some experience with urethane (blue) fuel lines in respect of life time vs the standard fuel lines?  I have been using for ex Trelleborg black/rubber lines that last from my experience minimum of 5 years. Then i have been hearing story's the urethane will outlast all standard rubber lines.

    Several years ago, while I was preparing to do the fuel system on the current project, I had simular questions. I made up endless loops of the available fuel lines, one set filled 50% full of ethonal free mogas and one set filled with 10% methonal. I hung these loops in an area exposed to direct sunlight and exposed to all weather elements. After one year all the lines except the blue urethane showed signs of deterioration, from minor to complete failure, the blue urethane remained unchanged. Three years later when I tired of checking on the test pieces, and threw them away, the blue lines still appeared serviceable. This was just a test of the products I had on hand not a market evaluation. It is sure an eye opener to see how quick some products deteriorate under those conditions though.

    Ok. Thank you :)

    I have had other similar answer´s and these fuel lines seem to be standing out of others with life time and ethanol mixed mogas, As ethanol free is not available here in Iceland. We are going to use them for our system.
