Re: How to pump old fuel out of built-in fuel tank
Depending on the size of the tank you could be leaving a quantity of water/fuel/muck in there as the fuel pickup is raised off the bottom of the tank. [links]
Re: How to pump old fuel out of built-in fuel tank
If/when the tank is low enough on fuel, I remove the fuel pickup completely and stick in my own hose, all the way to the bottom corner of the tank. [links]
Depending on the size of the craft, if it is trailerable or not, I jack and block the trailer such that the fuel tank is angled, the fuel pick up is on the lowered corner. Rig the boat trailer like this then let it set a couple of days, give it time for any water to completely settle. [links]

Whether it's diesel engine clean fuel or any other gasoline marine engines fuel, it's good practice to feed your boat engine with the fuel it needs. here
Some boats will have specific instructions when cleaning the fuel tank.
Install the new fuel filter too. here
This will have lots of benefits including improved boating performance, it will help with fuel-system maintenance. here

While this method is tried and true, it's not at all clean, and not entirely safe. Fuel is very combustible, and you never know when something could spark a fire. With a simple tube siphon, you run the risk of spilling gas all over, and this is a fire hazard. here
There are a number of reasons that you may find it necessary to drain all of the fuel out of your gas tank. The most common reason these days is bad gas. In the old days, "bad gas" meant fuel that was years old, contaminated with water, or was full of solid debris. It was rare to accidentally end up with bad gas in your fuel tank, although there were always reports floating around of people who filled their tank with bad gas right from the gas station's pump. But for the most part bad gas was a problem that affected people like farmers and antique car guys who let things sit for a long, long time then tried to take a shortcut by not cleaning the old fuel out of the tank or engine before they tried to bring some piece of internal combustion equipment back to life.
When most people think about siphoning gas out of a car or truck's gas tank, an ugly picture comes to mind. They imagine themselves sucking on a long tube with one end shoved deep into the fuel filler hole of their vehicle, hoping they can get the tube out of their mouth and into a bucket before the gas hits their lips. here
We recommend using a proper manual pump that is approved for combustible liquids like gasoline. If you go to the auto parts store you can find one -- just be sure to look for the combustibles approval, because many siphon pumps are not suitable for fuel. It's also recommended to stay away from the super-cheap versions that use a little bulb to start your siphon for you. The best equipment features a high volume hand pump which is completely sealed and comes with lots of tubing for both the gas tank side and the end that will go into your approved fuel container. here
That was the old days. These days bad gas has become everyone's problem. The addition of Ethanol to automotive fuel has changed the gasoline game for the worse. Ethanol-enhanced fuel has been causing serious problems in both large and small engines. Where old, ethanol-free gas took years to become unusable, new E10 (10% ethanol) fuel can go bad in just a few months. This is a real problem. Consumer Reports details some of their findings pertaining to E15 (15% ethanol mixture) gasoline.
I need some help. I can't seem to figure out how to drain the ethanol gas out of my 21' Sun Tracker pontoon boat. I guess I would make a terrible thief. more
I tried to siphon the gas out but I am not having any luck with that. Also I have a water/fuel separator inline between the tank and the motor. here

Do I need to buy a hand/electric pump to empty the gas out, and if so, how do I hook everything up?
