Plastic fuel line connectors- how to remove?

[wreckwriter]

I've got this tool:

but still can't figure out how to get the damn things off. Tool doesn't seem to fit, either one, so I think I'm doing it wrong somehow.........

Fuel line disconnect tools are of many.I am a tool man and sell many many types with subtle differences.I would be sure that tool includes the G8.

Supposedly it does.

Supposedly it does.

They are a pain to use. When I replaced the fuel pump on my truck it took me awhile to get the lines loose with the tool. Once you get the tool in there just right you'll feel it unclip and the line will just slide off.

[wreckwriter]

You used the tool in my link? Are they separate tools for different size connectors or are they used together somehow? Not much difference in size, blue one is a tad bigger but neither one seems quite big enough. Does the cone side go on first?

The one I used looked like this:

Some tools are just not quite long enough to release the fingers that hold the connection together.

Try this: push the connection together without the tool, then insert the tool fully into the connection and see if it will release.

I've had the most success with a black plastic tool from Pep Boys that looks like the KD tool above.

That is the tool GM specified in the service manual.

These are for a different kind of connector, like the one from firewall to rail.

Yea, only issue being that the tool doesn't seem to fit :/

So is this.

When I removed my GT intake manifold the KD tool worked.

As it will on that end. I'm at the tank end, different fittings. In any case, I got them off.

Which one worked, the red or blue? Or did you use something else?

[tchr49]

Don’t buy the cheap ones from Advance, they’re crap

[J Wikoff]

How the frick do you get the fuel line off to take the pump out? There is not enough room to get a fuel line disconnect tool in there.

[-Ray-]

Push, squeeze the tabs and pull. You may need to twist.

[J Wikoff]

I tried everything I could think of with the tabs. Broke them off after trying to pull at them with picks. Tried using the picks from underneath, like a normal disconnect tool would work if there was room for it, and broke the nipple off the effin bucket. Too bad I only ordered the level sensor beforehand. Looks like I'm waiting till Tuesday for a whole new sender/pump unit.

[-Ray-]

If I remember correctly, Pete had trouble with his too.

[J Wikoff]

I'm trying to decide now. I was able to get the nipple piece out of the connector now that I had the room to use the disconnect tool. So it seems like it will still hold fine. But if it ever had to come back off in the future, do I stand a chance of ever getting it off with the tabs broken off. What can I use to repair it with?

Maybe just replace the line section?

Mine was a reeeeal pain.

I've ordered the tool mentioned above (en46843), just so I'll have it in the future. But I don't think it will work on the connector with the tabs broken off. So I also got the Dorman repair kit below and a compression union. The Dorman repair fitting has a clip that is easy enough to remove without special tools. I've tested it with success on the broken nipple/post.

If I used the barb, I'd heat it and put a hose clamp or zip tie on it, though neither was supplied. I'm going to use a compression union instead. I think they are more secure, and easier to uncouple if needed.
