Is there a way to "flush" a gas tank?
I know the best would be to simply replace it, and failing that, some people have suggested removing it, putting BB's in and about a half-gallon of gas or something, rattling it around for a few, and then emptying it...repeat as necessary...
But I was thinking more like just unhooking the line before the pump, and then using a siphon or something to draw gas from the tank, then filter that and replace in the tank...then repeat until most of the garbage was sucked up from under the pickup.
Would that work?
Keep in mind that this is just going to be a driver, not a restoration.

You can drop it off at a radiator shop and they will boil it out, or do their version of a clean out.

Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first.
Life was a little easier when I was just a wrench.

Ok, well, then I guess I'm going to have to drop the tank.
Is there an "approved procedure" to doing this? Any pitfalls I should be looking out for? Howabout the pickup assembly, is there a specific way of unhooking this after lowering the tank?
What materials should I have on hand, for when I put it back in? I did some reading and there is mention of a "felt" of some sort which goes up above the tank. Is it possible to re-use these? What happens if you leave one out?
What about the bolts? I have also read that people routinely replace the J-bolts when they drop their tanks. Is this necessary, or can they be re-used?
Thanks for the replies, and in advance for any advice!
The POR company sells a product called "Marine Clean" which is really just super strong detergent. You put that in along with nuts/bolts or chain and shake--yes its tiring. You wont believe what comes out. You probably could do that on the cheap with laundry detergent. Rinse well. Dry really well. POR then sells "U.S. Tank Sealer" which is a thick paint-type coating that you poor in and rotate till completly covered. Eastwood also sells a product for this. Works very well and effectively provides a clean surface for your fuel, rather than decades old corroded steel.
Or...buy a repop tank
As far as the felt? Use roofing felt (tar paper) works fine, cheap

ive used the eastwood kit and it works great. they sell you the coating and the fast etch. you but acetone and muriatic acid. if you just want to clean it out (rust and varnish), just use acetone, some laquer thinner or berrymans chem tool b-12, and then use DILUTED muriatic acid. it takes all the rust off.
RINSE WELL and wear eye protection and gloves. that stuff is ACID

Replace it.
It ain't worth it IMO to spend money on a old tank that could leak/rust out at anytime.
You'll be miles ahead with a new one, they arn't that exspensive nowadays.

totaly depends on the condition of the original. If its a rusted mess then yeah, change it. Being as he is willing to clean it up , it's probably worth the time. Used to be this hobby was about spending "time" on your cars. The word expensive has different meanings to different people. Guess I am just cheap. I like to spend time. Any one can spend money.

with what your saying and I do feel good repairing my cars. But a gas tank is not a place to save money on, it could be dangerous and more importantly, the fuel system will be much more reliable with a new tank.

Hey, I'm willing to look into that...it's advice from experts, all this advice is, and if there is one thing I don't do anymore, it's argue with the experts.
So, how much would a new tank cost? Can it be had for less than $100?
Heck, if I'm going to drop the tank, wouldn't it make more sense to put something nicer in there than when I started?
Then again, I have no doubts about it...I am cheap, and the car is only going to be a driver. There are plenty of things to spend money on (suspension, steering, brakes) which rate slightly higher than the tank.
And again, "tanky" for all the advice and info!

I just went through all of this on my Dart. Pulled the original tank to clean it out and put in a new sending unit. Took it to a radiator shop to boil it out and seal the insides. That was $100. After I got it back, I worked for 3 weeks off and on trying to get the new sending unit to seal correctly. Always wanted to seep gas no matter how clean or tight the seal was. After all was said and done, I ended up buying all new pieces from Quanta Products www.gastanks.com and ended up spending over $400 for everything. It's all new from the pad, to the sending unit, so that part of my car is good for a while. Could have saved about $100 by buying everything from RockAuto.com They sell the same products at cheaper prices.

my tanks wasnt rusted. well maybe just a tinge of surface rust but that could have been varnish from old gas. my car sat for 10 years and all the gas evaporated and left a varnishy film. I didnt want any of that varnish coming loos and causing me problems so I got the kit. but yes, if you have serious rust to the point of metal thinning, replace it. the tanks are about $220
