Teflon tape or paste, which to use?
Be aware that at least the Teflon tape and probably the paste too, if used for the sending unit plate screws will/might act as an insulator preventing the meter from registering. I used Teflon tape years ago to seal the threads on a temperature sending unit in an A4 only to have the gauge not work. I removed the tape and used pipe dope(?) and it sprang to life.
