2004 Alero running rough, not sure if there is moisture in gas tank?

I have a 2004 Olds Alero (89,000 miles), and I drove to work this morning with no problems, except I was a bit low on gas. At 6:15 this evening I went to start up my car and it was reluctant to turn over, but did in less than a minute.

The car was shaking and idling very rough, and it’s a bit loud. No backfire, but its kind of got a putt-putt quality to the rough idling. I put in a container of Heet, the more intense one, and filled the tank. I drove the car home, for about 25 minutes, and the ride improved, but it’s still got the symptoms to a lesser degree.

How do I know how much gas is in a full (very full) tank?

I have a 1996 Pontiac Grand Am (6 cylinder 3.1 liter engine). I know that the owner’s manual says that the tank holds 15.2 gallons, but this isn’t really what I’m asking. I understand that the tank is supposed to be full when the pump automatically shuts off when you’re refilling the tank, but from what I’ve read, the shutoff point can vary between gas stations, and even between different pumps in the same station.

Easiest way to drain front gas tank on 94 ford f250?

The truck just broke down in the middle of the street so am racing around the clock to fix it. It does have 2 tanks on it. The rear fuel pump just went out and the front tank is full of old gas. Last time I tried to run the front tank it sucked alot of water and took forever to flush the line out so I know for a fact its full of crud, hasn’t been used in over 10 years! I am for sure the pump up front works so have decided to drain this out and see if I can get it to run on the front tank, what is the easiest way to drain the tank on these trucks? siphon gas out? drop the tank? is there a drain plug? any help would be appreciated.

Tips on cleaning motorcycle gas tank out please!?

Its an old tank, full of black grime, but not alot of rust. I tried shaking bolts inside with soap and water someone suggested to me, but this stuff wont budge.
Can I fill the tank with purpe power or simple green and just let it soak in the tank for awhile? Should I dilute it? Thanks!
how about if i just pour some carb cleaner inside, let it sit, and then rinse it out?

Is it water in the gas tank?

For some reason when we start our 1999 Ford Expedition SUV it tends to stall a bit. Then we will put it in reverse and back out and put it in drive and hit the gas the truck shuts off then starts back up on its own. It happens when we make turns and hit the gas to accelerate that it will shut off the whole truck then it will turn back on, but only for like the first 5 minutes of the drive then there isn’t a problem. It drives normally after that. Is it water in the tank?
