Hello members. This is in regards to the defective Lund sending unit gaskets. I did experience this problem on my Lund ProSport 1700 Adventure, that I purchased in June of this year. The problem was detected after I had filled the tank for the third time on a return trip. A couple days later I detected gas smell in my garage where I store it. There was a small amount of gas in the bilge. I traced it back to the gasket. The gasket was swelled and split.
Having years of experience with sealing gaskets in my work as a product engineer for the automotive industry, it was obvious the gasket was not compatible with gasoline. I did get it replaced a couple weeks later thru my dealer. The day I brought it in for replacement, the dealer informed me that Lund would be implementing some action on this.
I received the letter about the defect about one month after the replacement. Frankly, I considered the hazard potential quite high. In the automotive industry, Falure Modes and Effects Analysis considers the degree of hazard from a defect on a scale from irritating to mission disabling to life threatening. Concentrations of gas fumes trapped below the floor would seem to be a high potential for you know what. It’s been about two months now since the replacement. I have not heard any explanation as to the cause of the incompatible material, but maybe it’s time to give them a call. Anyone else out there have any problems? Other than this, I’m satisfied with the boat.
