    Want a new car

    I wonder if you could disconnect the fuel line like where the filter is and turn the ignition on and let the pump do its thing, probably wont get the last drop. Also thinking you could get at the fuel pump from the access inside the hatch and syphon it out.

    you can rent siphoning equipment from most part stores, stick it down the neck into the tank, and let it do it's thing....i'm replacing my fuel pump right now, had to pull the tank...fun job, but my dad has a Gas Caddy, so I didn't have to rent.


    p.s. there is no drain plug, so don't even look for one

    My Typhoon actually had a wire on the firewall from the factory,,,you stuck 12 volts on it and the pump would run,,,,great for draining the tank. And my Nomad has a factory drain plug,,,great idea to have,,,,

    I wish these camaros had them,,,don't know why GM stopped doing either of these ideas. In any event,,,I would unhook the fuel line,,,stick a hose on it to direct the fuel right into a can,,,turn the key on and let the pump do it just like suggested,,,,of course that is if the pump is still working????

    Of course these things never die when you are conveniently low on gas,,,,and with a dead pump you can't use it to pump it out either,,,,lol.

    So there is no anti rollover valve in the filler neck?

    Go to sears and spend $18.00 on a Craftsman Siphon System It's kind of a pain to use but once you get it working it'll do the job.

    I didn't think the check ball in the filler neck would let you syphon gas the old way. I personally haven't had to drain mine, I just ran it near empty before pulling the tank. I would either pull the line off going into the filter or put a line on the end of the fuel rail and use the pump to empty it. You pull the shrader valve and put a piece of hose there then jump the pump at the fuse block and let it run. Probalby not the easiest thing to do for the pump but it'll work.

    When I installed my racetronix fuel pump I used that craftsman siphon kit. After a bit of wrestling with it I got it to work just fine and emptied out the tank so I could drop it. But as far as I can tell there wasn't any check ball. I could be wrong but don't they only put check valves on trucks and suv's?

    Service manual says to use siphon type tool.Do not try to use pump itself to run it out or it could damage pump.There is no check valve but a flapper door kinda thing.If I had to do fuel pump I would seriously consider cutting a floorboard access hole.I've seen info on the web that shows exactly where to cut to be perfectly positioned over pump!

    Well the only reason I ever drain the tank to remove it is when I am changing the pump anyway,,,,so why would one be worried about damaging it???? Or is it just me???? I've done it this way for years

    I couldn't bring myself to cut into my baby...just seemed wrong to me....on the other hand, if I ever have to change my fuel pump again in the next 100,000 miles, I may consider it if I'm working alone...with help it only took about 1 1/2 hours to get it out....now i'm waiting on the right pump, because O'reilly's is reeeeeeetarded. I got one on eBay brand new for 180.00 instead of the O'reilly's 361.99...Definately worth the wait, and still comes with a one year warranty, BAM.

    Can't get a siphon hose down the filler neck. Tried two different hoses, both hit something 22 1/2 inches down. Disconnected the inlet to the filter and jumped the fuel pump relay. Made a big mess and discovered my sneaker's soles melt in gasoline

    Thanks for all the ideas,

    Al

    several feet of fuel line hose, a clamp, and a bucket would've saved the mess. At least you got her empty though.
