Whats the best way to Drain your Gas...? Options

[914werke]

Semi full tank ...Oh this is a late car if that makes a difference.
Any tricks?

Points? If you have a pertronics this isn't a good idea. I just unhooked one of the fuel lines after the pump and turned on the pump. Works great and gets most of the gas out of the tank. (IMG:style_emoticons/default/beerchug.gif)

Pump it out using the stock fuel pump ...

(IMG:style_emoticons/default/agree.gif) with Jon and Andy. Let the fuel pump do the work for you. I hooked some tubing from the fuel pump and just ran it to the tank in my truck. Easy-peasy.

If you are still using the stock Fuel Pump relay to power your fuel pump,
you can simply pull the T12 connector and hook up 2 wires on the relay board
and it will energize the fuel pump relay and power the fuel pump.

By doing this "trick" it will not energize your coil, points, or anything else
on the ignition circuit.

Power and Ground are supplied to the fuel pump relay which cause it to
energize and then the relay switches a live fused power connection to your
fuel pump.


Attached is a picture of where to connect the power & ground.
When you do this. DO NOT insert the key or turn the key on
and make sure to disconnect the T12 connector.

Be very careful not to bump/tourch the lower 2 pins of the T4 connector
with the +12v because that will attempt to activate the starter!

Once these wires are connected the pump will run until you disconnect
them so make sure to keep an eye on things so the pump doesn't run dry
for very long.

Gee, I used an old school siphon. But then again, I like the taste of gasoline and I don't smoke.

Did the syphon thing on my late style. Early stlye pulled the feed line to the pump and drained it that way. I guess if you have enough line on your feed to your 75 pump, you might be able to pull it without out making too much of a mess if you dismount the pump and do it from underneath with the pan off.

Uhm, guys ... The fuel line goes to the engine. Take off the fuel line on the engine and route it into a big can, then jumper the relay like posted above and let the fuel pump do the work.

Can't get it any easier than that ...

I have a Pertronics and getting ready to drain the tank. Why is this a bad idea? (IMG:style_emoticons/default/confused24.gif)

You need to disconnect the ignition or the power to the distributor or you will fry the pertronics. The electic jumps these guys above were talking about is how you can get around thatthough and you will not damage the pertronics.

Thanks for the quick answer! (IMG:style_emoticons/default/smile.gif)

Inside the distributor there are points or an electronic ignition circuit like the
pertronix that act like "points". Each will close (short) the coil lead to ground
as the distributor rotates.
The points are mechanical and the electronic devices use an electronic trigger.
In the case of the pertronix, they use a magnet.
When the sensor "sees" the magnet, it connects the coil lead to ground.
The problem for devices like the pertronix is the combination of their design
and unlucky engine rotational position when not running.

The early pertronix design (I believe this was fixed in the Pertronix II)
grounds the coil lead while the magnet is "seen" rather then just
a brief amount of time only when magnet is first seen.

When the engine stops, it might stop at a point that the distributor is positioned
such that the sensor is directly over the trigger point.
On a pertronix, this means that it continuously sees the magnet and
is stuck grounding the coil. The full coil current is
being handled by the module. The module cannot handle this much
continuous current for extended periods of time. It overheats and kills it.

This is why people warn about leaving the ignition on burns up
pertronix. It actually depends on where the engine stops.

BTW, this same issue exists for points, other than points don't burn up.
However, even with points it is possible that a coil could get very hot.

On this subject where would you syphon the gas into.

Any good ideas for containers ?? One of those 5 gallon Arrowhead bottles or something from harbor freight sells ??

And what would be a good place to dump the used gas ?? Would the local auto parts store take them ??

Thank in Advance.

Give your local town/city hall a call. They should have a hazardous waste site open during certain hours for the public.

Quick google search brought this up

Hyperion in El Seguendo recycles old gas. Bring it in on a weekend and they'll take it. Entry is on Imperial, just east of the Ocean.

Every couple of months there is a Community Re-cycling effort. They

will re-cycle old gas for free up to 3 gallons. If you have more than

3 gallons, its $5 a gallon. It took a year for 16 gallons......over here..

[r_towle]

I mix it into the lawn mower gas...the blend depends on how bad the gas really is.

If its really bad, I dispose of it.
