Trash in fuel
 

getting trash in fuel filter and carbs , little black particals, thinking the hoses are breaking down,and backwashing back into the tank when not in use, with 140 gal of fuel in boat, what are my options, need to replace, pumps, hoses, and clean tank, damn ethonol , how do you drain out that much fuel ?

pull the sending units out and get a pump that's RATED for gasoline, you might be able to strain it and run it in your truck and cars

I would just add a fine micron fuel filter that can catch the stuff.
