How to disconnect vacuum connectors?

I don't want to bust anything. How do you go about disconnecting these type of connectors? This one is at the gas tank, where you can see the crack I'm dealing with...

The white clip should pop out and then it should just slip out.

Push in on the white clip!! It will slide out with some twisting after. I fought mine for awhile, as my brain kept telling me it needed to be pried out.

Also, that is a check valve for the anti-roll over. There is a great video for a quick and easy repair, using a .20 plastic dowel, an 11/64 drill bit, and some pvc plastic cement. It took me less than an hour to fix, and I didnít drop the tank.

Hereís the video:

Thanks. For now I used JB Weld plastic bond and attempted to seal it. It was not broken off, just a crack on one side and still mechanically sound, mostly (not wiggly at all). It has been good for 2-3 weeks or whatever it's been since I posted. If/when it cracks again or comes off , I'll try this method. Are you sure PVC cement melts this kind of plastic?

If you havenít done so already, cut the factory zip tie by the tank and replace it with one thatís longer. I think thatís whatís causing it. It puts a pretty big strain on it. I was told the plastic cement would be sufficient. To be honest, the plastic dowel alone was probably enough to fix it. It wedges in there pretty tight. The plastic cement was just for peace of mind.

that video may show it but due to a seemingly large amount of these cracks in the antirolll over and those evap lines running into fuel tank there ( im not the originator of this but fwiw it’s a good idea ) as long as OP has that off, take a look at how that as well as the filler hose have the e- brake cables running OVER TOP of them.

Somebody mentioned it ,iirc, so I checked my rear at extreme downtravel of suspension and sure nuff the emergency brake lines were about to snap them off.

I ran that line and filler hose over top of brake cables so it could not contact and break those things off . It’s simple & easy to do as long as you’re replacing stuff under there .

Maybe that’s how yours cracked ?

As mentioned , for the quick vacuum line connector that you’re showing, its connector has a squeezable little top third of the edge that you depress and then pull and it’ll come off. The white nozzle has a little oring the pressing allows you to release ...
