Bah, you guys win again. I don't wanna do this again.
I'll be getting a new Delphi FG0324 fuel pump so I guess by extension that means I'll be getting a new o-ring (or gasket?).
As for the lock ring, I'll have a new one nearby if I don't like the look of the old one.
Did you drop the old tank yet? Hopefully you won't go through what I did with the rusted and frozen fuel line connectors. Just a heads up.
