need help...what is the best way to take out old gas thats been sitting of hella long?

 

How much is in the tank?

 

You can either drop the tank and be careful if there isn't too much fuel in it, or you can try to syphen the gasoline out with a hose of some sort.

 

theres a liittle more than 1/2 in the tank

 

I hear fire works well.. But don't find out for sure.

Don't most newer tanks have a screen or a block for that?

 

does it have a drain bolt.

 

Siphon it out.

Works well - I do it all the time.

 

Siphon it out, refill with fresh.

How old is it?

 

A lot of the new vehicles have a screen so that you can't siphon it out. I do know that some manufacturers put drain plugs in the middle of the gas tank on the bottom for such occasions, but I believe this isn't used anymore because of the area around the plug rusting out. The only way to get the gas out of the tank is really to drop it and pour it out. Also, many of the new gas tanks are plastic now because of the problems vehicles used to have with gas tanks rusting out. But yea, how old was the gas? Usually after sitting for a month or so causes it to go bad, especially if it's sitting in an open container.

 

the gas in the car is more than 2 years old

 

it's in a 95 civic i havent got under the car to see if theres a plug

 

take the cover for the fuel pump off under your rear seat. then syphone it out through there really easy. i actully used a wet/dry vaccum and just sucked the gas out from there. maybenot he safest thing but it worked. you might need to remove you fuel pump as well. but this is a much easier option the dropping the gas tank. and gas goes bad after 3-6 months depending on the make of gasoline.

 

I want to say there's a drain plug on the fuel tank. I'm 90% positive.

 

There is a drain plug (atleast on 96-00 civics), but the plug is covered in some kind of anti-rust type retardant from the factory which tends to come off when you unscrew the bolt. I'm not positive, but I doubt it is a good thing for that material to come off and expose bare metal. I would do it the way afstvx suggested if you can't get a hose through the gas cap way.

Edit: I didn't make this clear: afstvx's suggestion.. minus the vacuum. Just use your mouth to syphon it

Your 95 Civic's gas tank has a drain on its bottom-rear. Jack up the front of the car, put an oil pan under the drain, undo the bolt, and drain away.

 

as long as if the fuel isnt dirty, just go and top off the tank, the new gas will mix with the old, may not be the best, but it will work till you finish off the tank. i had an old pickup that had been sitting for almost 10 years in my back yard with a blown motor, when i got a new motor for it, i used the gas that had been sitting in the tank. ran a little rough but wasnt to bad, just change your fuel filter after that tank of gas, wont have a problem. with gas being like gold now days, why waste it? and do you even have a safe place to dispose of it?? the only thing you have to worry about is having water in your tank.

i agree if there no water or rust in the tank just mix it with new gas.. i did n works fine i still have about 10 gas containers from years ago in my shed, when we had gas shortage around my area

Oh man...MAYBE not

Even the smallest spark inside that vacuum will blow up if you're sucking gasoline. I bet the user's manual for the vacuum will even warn you not to suck up flammable fluids.

I believe mythbusters tested this out, as well...

 

thanks for everyones i appreciate everyones comments...i got i done i just opened up the drain plug from the bottom took most of it out then mixed it with the new gas
