Bottom line is that if your boat sat for a while particularly in a warm region, you have something growing in your tank. Alot of the stuff will adhere to the walls of the tank, when you move the boat it breaks free and gets picked up in the filters, clogs them up and well, you know the rest.
They have stuff that you can add to the fuel that will kill everything in the tank...however the dead bodies sink to the bottom so you need to filter them out.

Big boats carrying large quantities of fuel (mainly trawlers and comm boats) have on board fuel polishing systems. These essentially filter the fuel (or polish) constantly, 24/7 , ensuring that your fuel is in top condition.

I picked up a boat that has been sitting for a while in Florida and I just know there is bad %$%$%$%$ in that tank (diesel) and before I run it I want the tank and fuel cleaned. It is a larger problem with diesel than gas but I have heard it can happen in both fuels.

I had read about this and was just wondering if anyone did it up here.
