A warning regarding ABC banjo bolt orientation (to avoid an ABC fluid shower)

Make sure you take pictures of the orientation of the ABC banjo bolts (their lines specifically) before removal/reinstallation!

I reinstalled mine with the top one's hose trailing, and the lower (deadend tube) banjo leading (in orientation to the front of the car), which is the incorrect orientation. Tightened everything up, started the car, and lost ~1.5L of fluid in about 4 seconds. Fantastic. Really nice. The top hose is interfering with a pice of metal directly above it, not allowing the banjo bolt to seat. This is not an issue with my CL55, as it's ABC pump does not appear to stack two banjo bolts on top of each other.

Pic below is the correct orientation that I found from a Youtube video, after realizing I forgot to take my own photos. The green arrow points to the metal that will cause banjo bolt seating interference if you install the lines the wrong way.

Also, there is a copper washer in between the two banjo bolts' orings... forgot to mention that.

Correction, NO copper washer.... The one sitting on the pump's pressure regulator thing somehow came from something else, despite being a perfect fit for the banjo bolt.
