I thought about that as well. However, I would think it would be leaking somewhere wouldn't it?

On a side note, I grabbed the fuel filter that I pulled off of it on Friday and looked in side of it. There is detritus in the bottom as well as what appears to be rust. I haven't cut it open to verify what the junk is. The tank itself looks super clean. It's a 100 gallon tank and I can see both pipes and the sending unit as well and everything looks great. Nothing is in the bottom of the tank, nothing is floating, the stand pipes are both unobstructed.

I am confused now more than I was before.
