best way to drain bad gasoline
« on: September 28, 2009, 09:51:26 AM »

The '71 F3 has about 10 gallon of bad gas in it - didn't see a drain
plug... back in the '74 fuel shortage you could buy a hand turned fuel
pump for transferring fuel - can you still get them and where? It'd be
handy to have one around... I know not to suck on a hose to start it,
and I don't want to drop the tank right now though I will eventually.

I might suggest you remove the tank and drain it.  You may have rust in there which will call for the eastwood lining kit or send it out to a shop.

Yeah, I did that for the '58, and relined it with Eastwood liner, and
intend to do so on the '71, but for now I just want to do a quick
fire-up to see where I stand.

I use a length of clear vinyl hose attached with nylon wire ties to a long dowel so I can place the end (curls up) right where I want it in the tank. Then I blow compressed air with a blowgun past the end until a siphon is created. Jack up the rear end so the gas runs to one end.

Just a bit off topic,if you wanna run the engine.
Use a jerry can and a hose and hook it up to the fuel pump inlet just to get her running.
As for the bad gas,dropping the tank and treating it is the best way.
Acetone works great for breaking up the varnish build up inside.

Bob - you mean you blow compressed air in the filler neck until the pressure forces it out the hose?

nope, blow the air across the end of the hose (the way a spray gun works)


in a pinch you can fill the hose with gas and quickly put your finger over the end, then lower the hose into the bucket and take your finger off the end. I do this with water for my fish tank siphon.

Drop the tank, and pour the fuel in a container.
 
If you dont want to drop the tank: Disconnect the fuel line before the pump. Connect a compressor with a paint gun to the fuel line, and the compressor will do the work for you. Make sure you store the "old" fuel in a safe container. I did the same to check if I had any dirt in my fuel tank a while ago.
 
Chances are that your tank still needs a new coating, and this is work for a specialized shop.

Ah yes Bob, the Bernoulli principle (I'm an old science teacher after all)... that should work fine, an excellent idea!



Eastwood sells the coating, basically you just pour it in and slosh it around 360 degrees. Did it on my '58 DeSoto.
