First, you need to find out where the water got into the fuel tank and fix the problem. In an older boat, fuel hoses and the sender gasket degrade and can lead to leaks. The o-ring on the fuel filler cap is a very common place for water to get in.

To pump out the tank, you need to fashion a safe fuel pump and filter rig or hire a fuel polisher. Open the tank by removing the sending unit and then use a copper pipe attached to the fuel pump hose to get into the corners.

If you open the sender I would replace the gasket.

Age of the boat will determine how far you need to go. An older boat is likely to have at least some gunk in the tank.

As a result of Covid and multiple immediate family deaths my 2310 has been under wraps for a long time. I am finally able to get back to it, but the fuel in my tank (150 gallons) is three years old. How do I get to the sending unit to open it up? Is it one of the access holes in my deck? I plan to empty the tank because the engine is new and don’t want to even try that old gas. The bot is on a trailer and the gas tank is fine but I need to replace the fuel. I am open to any thoughts. Thanks

Gently pry out the deck plates. One of them, near the center line of the boat, will cover the fuel tank sender. The other will cover (on the side of the boat where the fuel fill is located) the spot where the fill and vent hoses connect to the tank. The sending unit is held down by screws and you need to be very careful removing them. They could be tough to get out and you definitely do not want to strip the heads nor the threads!

Make sure there are no sources of spark or flame present when you take that sender out! Safety first.

I have a center console and that is what I am describing. You have a pilot house so the locations of those deck could be slightly different.

You may consider a tube of USS tefgel and put some on the sending unit screws, and anywhere else aluminum and SS interface (my 2019 engine bracket ladder screws were beginning to corrode to the aluminum). Messy, sticky effective stuff.

Thank you!

I had a problem with debris in my tank that clogged the anti-siphon valve. To drain the tank of approx. 50 gallons of gas I used a fluid extractor, like the ones West Marine sells.
To get to the debris I used a small mirror to look around the tank and a piece of 3/8" clear tubing wire tied to a large paint stick. The tubing ran past the end of the stick about 7" to get into corners.

Where did your debris originate?

I'm not sure Bodick, I bought the boat about two years prior and many things had been let go. The water separator was rusting and hoses had not been changed in a long time. Changing the hoses may have caused it or prior negligence.

What to send an update I get the tank drained with an electric pump and a holding container . . Removed sending unit and with a flash light some clean rags . I was able to soak up all fluid from tank . I had a running problem that turned out to be dirty carbs . The main jet is and the bottom of the bowls
Collecting all the dirty . Thanks for all the replays

I did put a new o ring on the fuel fill
Just to make sure water didn’t get in there it was Dre’s out and deformed
