I have a 1991 19' Outrage. When the boat is completely full of fuel and jacked up on the trailer I find fuel in the back end of my boast by the wash down drain plug. After I run the boat each trip I empty the water separation container and it always has some water along with debris. I then pump out a little more gas to remove more water and debris. Looks like little rocks but may be rust. I replaced the decking last year and the tank looks fine, clean shinny aluminum. The fittings into the tank look corroded and the hoses look old. Do I need to replace the tank, fittings, and hoses or pressure test and look for leaks?

Many times water in the fuel is a result of a bad clamp.

I would replace the all 3 hoses (vent, fill, supply) and the clamps first.

Hoses may look okay on the outside but degrade on the inside. Note that all new hose is alcohol resistant.

Thanks for the reply. What are you calling the clamps? Hose clamps or the fittings screwed into the tank that the hoses attach to. What would cause the debris getting into the tank?

The clamps are the stainless clamps attaching hoses to the fittings. The supply,vent and fill fittings are welded to the tank.

I think the debris could be from degraded hose and/or from the wire reinforcement inside the hose that has corroded.

That makes sense. Thank you
