I had stored my bike with fuel for about two years with a near full tank of gas. The fuel pump was dead when I attempted to start the bike up, today as I was changing the pump this is what I found in the tank after draining it.
The fuel looked slightly dark and had a very stale smell to it. The accumulation was the consistency of sand and washed out easily. The fuel hose that was submerged from the pump to filter was very soft and separating internally, the hose at the top of the tank post filter looked very dry rotted
If it wasn't from ethanol, what could it be and how do I best prevent it from happening again?
