Fuel Line Fittings
The large scissor tool works best on garter springs; the small scissor works best on quick-disconnects. The only approved lubricant for fuel system O-rings is clean motor oil.

DO NOT USE SILICONE GREASE on any part of the fuel system. It does NOT dissolve in gas, so it can block the fuel filter &/or injector screens.

These fittings are known to stick when fuel deposits build up between the O-rings, making it very difficult to pull them apart. But pulling them apart (WITH the correct tool inserted to hold the garter spring out) is the only way to separate them. After they're apart, the deposits can be cleaned (Berryman's B12 is very effective) to make assembly & later separation easier. Again: the only approved lubricant for the fuel system is clean motor oil.
