Nozzle lines
Yes you can typically bend them by hand. If you have a fairly tight bend say near the injector nozzle use a 1" socket to bend the line around, unless you have a small 1/8" tube bender which works good also. Lycoming SB 342B calls out a .62 R minimum and a straight section from the end of the cone to the start of the radius of .69. Hope that helps.
