I had rust issues with my gas tank a couple years back so I took the dive and tore the bike down and did a reseal using the Caswell epoxy treatment. That was a new product for me to use and I wondered about the long term results. I've had some failures before with other products.
Every spring I pull the sending unit to inspect the tank and it has always looked fine. It's like a Thermos bottle inside with the epoxy.
But I figured the true test would be the fuel filter itself. So while I was changing plugs the other day I changed the fuel filter. So with a bit over 12,000 miles since the last filter change I was happy for find NO sediment in the filter at all. Nada. That was a first.
So if anyone is considering treating their fuel tank........ Go for it. The long term benefits are worth it. Not a single carb issue since the treatment. It's worth the time, effort and money to get it over and done with.
