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.

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.

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.

Pull the connection apart.
Using a clean shop towel, wipe off the male pipe end
Inspect both ends of the fitting for dirt and burrs.
Clean or replace the components as required.


Installation Procedure
Caution: In order to reduce the risk of fire and personal injury, before connecting fuel pipe fittings, always apply a few drops of clean engine oil to the male pipe ends.
During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.
This will ensure proper reconnection and prevent a possible fuel leak.

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