but you have all missed the point,a plumbed in AFFF system will 98% of the time not put a fire out,it just delays it enough to hopefully get the crews out.thats in a rally car wit no interior trim,carpets,plastic everywhere etc,so even less effective in a road car,complette waste of time,effort and money,buy either a proper gas discharge type for about £1000 or "find" a halon one,not illegal to have,just illegal to sell now,halon puts fires out!
