Exactly where have people pointed the nozzles from their plumbed in system?
I've sorted a location pointing into the driver's face

, the one in the engine bay has to be at the location most likely to catch fire yarr?
On an SR20 thats usually around the turbo as the oil feeds split and pee hot oil all over the wrapped manifold and it all goes up in smoke. However didn't EDC used to specify that the nozzle had to point at the fuel side of the engine - i.e intake manifold/fuel filter/injectors?
