Long story short I have water in my gas tank, about 1 gallon. Is there a way I can drain the gas tank in its entirety without removing the tank?

5.3L suburban 2002, gas 4wd automatic.

or are there any additives you would recommend me using to get it out, right now the truck has 15 gallons of gas and ~1 gallon of water in it, it runs, but at this point its random multiple cylinder misfires

Loosen the fuel filler cap in order to relieve the fuel tank vapor pressure.
Raise the vehicle.

Loosen the fuel fill hose clamp at the tank.

Disconnect the fuel fill hose from the fuel fill pipe.

Use a hand or air operated pump device in order to drain as much fuel through the fuel fill hose as possible. (auto parts store)

I'd try the pump method first. Once you get out 95% of the fuel, you can add a few bottles of dry gas and a few gallons of fuel. Repeat for a few days. Pulling the tank won't be fun.

'02 do. It would take quite awhile through that. Buddy of mine had a vacuum pump that he used for his boat. Just push down, pull up, and the gas would flow. Think it said not to use for gasoline, but it worked and only used it once.

BTW, how did a gallon of water get in there? Pissed off ex?

That or he's got a little kid who found a gas can in the garage, filled it up in the kitchen sink and pretended to be a grown up by filling the gas tank :jester:

if it was a pickup id just suggest takin the bed off and pumping it out.. but IMO the way to get all of it out for sure would be to take the tank off and drain it

I had to drop my tank in my blazer to do the fuel pump but I just shoved a hose in the tank and did the suck and spit.

I guess there is a plate or something in the newer vehicles that prevents that tho.

Disconnect the filter hook a rubber hose up to it with a clamp long enough to go into a gas can. Then turn the key and have the fuel pump pump it out.

This was money! Thanks for the tip!

Now I just need to figure out where to dispose of old gas.
