I opted for a not so typical install.
I
used to have a pump and tank (SMC kit) both behinde the drivers headlight.
That just got too gawdy for my taste and the pump was not doing too hot. Plus I wanted to hide the parts while keeping it as functional and accessable as possible.
So I went with the Devil'sOwn pump and trshed my old pump and tank (1L)

...
I ended up taking the front bumper off and going with a tap in the bottom of the coolant bottle (MUCH bigger now)
... ran the line through the front bumper...
... and mounted the pump in the drivers side front bumper near my FWI.
The line then simply runs up into the engine compartment and to the TB where the spacer has the nozzle assembly and 90* elbow etc.
