Hey guys. Just curious, to remove the intake manifold, how to I remove the fuel lines? I think I can figure out most of the other bolts/hookups, but just not sure about the fuel lines.

Also, last time I changed the Opti, I tried to get the balancer hub off to maybe convert to vented. Well, this time, I want to change cam/heads/opti so I need to get it off. Last time, I broke 2 balancer pullers, and the balancer hub didn't even move. Yes, I took that bolt out of the crank. What did I miss? Thanks guys.
