How to Replace Fuel Lines



2001 K2500 Suburban with 8.1L and dual fuel tanks. I need to remove the fuel lines and there is a retainer that secures the fuel, return and evap lines in a clip that is mounted to one of the bell housing studs at the top of the top of the transmission. I can barely see the bolt let alone get a wrench on it, how is it accessed? Also fuel lines seem trapped by the torsion bar, does the crossmember need to come out?
