I just did mine.
I found the best tool were crowsfoot flare wrenches. It's a bit tight down towards the back, so using a crowsfoot with two extensions and a u-joint did it for me.
I also had to use my Ryobi 1/2" impact wrench, but just for a second. Mine were really frozen and had a day's worth of PB Blaster on it.

Again -appreciate all the advice and tricks - will wait for the wrenches and have another go. Continue on with other refresh items while I wait for the wrenches, Thanks again

Spray the crap out the fittings twice a day while waiting. I now spray them over a period of weeks every time I'm out in the garage. (Get a good penetrant). I gut my soft lines to get a socket on them, finally they cracked. I had rust on the hard line so ended up having to replace it. Be patient and good luck!

If you cut the rubber lines, make sure you have some sort of cap/cover to go over each exposed end. Especially, if you still can't get them apart or are waiting for new lines to arrive. Usually, once I've cut the rubber line...I am committed to finishing the job come hell or high water and have freshly made-up ones for replacement.
If you have new lines in hand and it comes apart promptly...you are good to go...no caps necessary.

I agree with 'Don't use heat on a fuel line'...The idea of heating is to get one part to expand and 'break loose' Differential Thermal Expansion Usually you heat the 'female part' to expand it. Instead spray something VERY COLD on the 'male" part of the fitting to make it shrink. I spray computer dust-off on bolts etc. to loosen them. Hold the can upside down. The liquid (Diflouroethane) comes out so cold that frost will form on the bolt head!! Try that on the fuel line fittings a few times with the wrench on the female part to act as a heat sink. Just do it outside and stand up wind.
