hi, what's the trick to disconnecting the quick releases on fueline to fuel pump and electricalharness to it?

You need the tool for the fuel line connection. Check at a decent auto parts store.

You will need a "fuel line disconnect tool" about $9. The wire harness has a lock pin to prevent inadvertent disconnect. You have to pull the little lick perpendicular to the wires. The little plastic clip has a flat on it to help pull it out. It's usually best to soak the connection with WD 40 then blow it out with compressed air. This removes debris and dirt and makes it easier to pull out. I would suggest go to auto parts store have them get one out of box and look at how the clips work.

you should have a quick release tab, make sure you empty the pressure in the fuel rail and tank first. (Gas cap off and press shrader valve on fuel rail) ----- safety glassed required for next step--------- 2 tabs on either side of the end squeeze together push line forward and pull back should disconnect immediately

oh harness use a flathead screwdriver on the red tab and push back side to unloick, press tab down a remove connector.
