Fast Transport

I'd like to know if the unit being transported can still fire from fast vehicles that moved at cruising speed.

First I looked up Transport which tells me the following:

FIRE POINTS
Models firing out of a vehicle that moved at Combat Speed count as having moved that turn. Models firing out of a vehicle that moved at Cruising Speed can only fire Snap Shots that turn.

Then I went further on and discovered that fast vehicles have a different rule regarding shooting, but it does not state anything about the passengers.

SHOOTING WITH FAST VEHICLES
Fast vehicles that moved at Combat Speed in the preceding Movement phase can fire all of their weapons, just like other types of vehicles that have remained Stationary. Fast vehicles that moved at Cruising Speed can fire up to two weapons using their full Ballistic Skill – other weapons can only make Snap Shots.

I've got 3 Grotesque's and 1 Haemonculus on a Raider. Secretly hoping that I can move 12" and still shoot 2 of their Liquifier Guns. On top of that, I can't really find anything on Tank Shocking disallowing further shooting from the same vehicle, apart from the rules regarding the travelling speed. Even if I could only move 6" regular Combat Speed, I'd still be allowed to shoot those Liquifier Guns, but can I first Tank Shock and then have the passengers use their weapons?
