Big thanks to everyone that encouraged me to keep flaring and especially to the member that suggested I flip the flaring vise over. I can now bubble flare and I have 1 piece of my fuel line done. I managed to get it installed into the cab! *I had to cut out the rubber grommet to get the space to push it through but I think they made new ones of those.
This piece of fuel line is not yet bubble flared on the top end (but it is now).
