While you're replacing the lines, it makes sense to change the check valve. They're relatively cheap, and known to get sticky. The plastic seems to not like the new gas.
Doing a quality crimp is really hard for a home DIYer to do. I'd have someone with a real crimp tool do it. The only line that I'd feel comfortable making at home is the straight line that feeds the fuel pump.
Change the copper washers.

Gotcha
Copper washers...what copper washers? Plastic check valve, wtf is that thing? Thought there was one in the pump? There's another?
How the EFF do you access the soft lines in the tunnel that go to the hard at the trans?
If all the lines had the flared fittings I'd be more comfortable...this crimp nonsense keeps me up at night with fuel.
This do it at home having never ventured into fuel line territory before...to some it sounds like an adventure. To me: someone else should do it so I have a piece of mind and don't screw up my car trying.
