Is there an easy way to drain a half full tank without removing tank?

Can it be drained at the gas filter or at input to fuel injector?

What are you trying to do here-get to the fuel pump or bad fuel?

Bad fuel-disconnect the fuel filter run another hose to it direct the other end to a 5gal container-activate the fuel pump by using direct power from battery positive to the gray wire at the fuel pump connector.

Thanks for the answer. I am trying to get bad fuel out.

I found the fuel filter but I can't get the connectors off easily. I don't have the greatest access but I think it's decent access (some folks have suggested taking the wheel off, but I don't think that's the real problem). I think the connector is blackish and I think it has some kind of spring loaded latch (can't really see that well due to locale ibehind wheel well)

Is there some standard little tool to remove these? I think the hose is about 3/8". I guess I need to depressurize the system as well.

I think the fuel pump is in or very close to the fuel tank and I am trying to avoid taking that out, if I can.

Thanks

You need a special disconnect tool for your model

Rasmataz. You're fabulous! I have looked all over the internet for this answer. You'd be surprised the number of people who said I need special open ended and flare nut wrenches. Didn't seem to make any sense to me. Thanks again.

That being said. Where can I buy this disconnect tool? Would it be easier to disconnect at the fuel injector inlet (I actually coulnd't figure out what was in and what was out). I also couldn't figure out how that disconnector worked.

And one last question if I may. Do I need to depressurize the fuel line before removal? The owner manuel doesn't show which fuse runs the fuel pump

Thanks again

If you can do it at the fuel injector inlet/fuel rail go for it-just be careful-I don't think you need to depressurize it-but leave gas cap off-while doing it.

I guess I don't care where I drain the line. I looked at the link below and couldn't find a tool to remove the line at the fuel filter. That was a fabulous diagram you gave me and it does look exatly like that. Can I buy a tool to remove the fuel line at like AutoZone or something like that?

Alternatively, I've never disconnected a fuel injector. The 2 connectors looked like a metalic conical piece and I couldn't figure out how to release it without damaging it. There was no obvious bolt, release clip or anything to engage.

Finally, Is there an obvious way to tell which fuel line is in and which is out? And for that matter, does it matter?

Thanks!

Look for a return line going back to the top of the fuel tank.
Which one is out or in-the object is to take out the fuel

Parts store should have it and don't throw it away when your done-you might be needing it or a friend.

Rasmataz! You are right on all coutns. Autozone had a GM removal tool for about $8. Everything else was as you said, drainage went great.

As per your advice, will keep the tool for a friend in case they ever need it. Actually, you probably know this but supposedely can use the tool for some A/C lines as well.

Thanks again
