bummer.. gas tank liner peeling. ruined my day.

[what?]

I guess I’ll be doing the same. When I squeezed the rubber crossover tube when I had the issue it sounded crunchy. That was a few years ago. I looked on a few other sites (HD) etc and saw similar issues so it’s not isolated to BigDog. Anyone know what vendor supplied BD with the raw materials. I ask because in Pharma there can be lot to lot variability with incoming raw materials and certainly when switching vendors. Or is it just flawed technique of sealing overall.

I think your better off without the tank liner, the tanks are pressure tested to 10psi. Some will tell you the liner is to seal any pin holes in the welds, that's hilarious. The ethanol in the gas is nasty stuff I add Sta-bil over the winter, you can also use Sea foam. I just sold a car that was 37 years old and the tank material wasn't near as thick as the material used on the BD tank and it wasn't lined and it never leaked. I believe having a liner its a lot of hype.
