New header... questions about install

Putting a new header on this weekend. If I take the injectors out (I have O-rings) Will I still have to relieve the fuel pressure?

you really should. If you can take teh fuel rail out intact with injectors still in place and NOT unhook the fuel line you "should" be OK but it only takes like 20 seconds to relieve that pressure.

If you remove them from the fuel rail yes or if you disconnect fuel line from the rail. You can pull the fuel rail with injectors as an unit. No big deal either way, simple to drain at the schrader valve on the fuel rail.
