I never thought I would see the day that Jeff was running a swap. Another of the NA old guard bites the dust. RIP...
But congrats on the new life. If it's any consolation, I too reversed those fuel lines, once. I was tired and had been at it for many hours over two days. It happens to the best of us.
Though my all time Swap-No-Start bonehead move was not bolting the SMJ together. That took a ridiculous 2 hours+ of troubleshooting to figure out. It's such a kick in the arse to do a swap 100***37; correct and then not have it start because you couldn't plug in a single plug correctly...
