Heater tap
On the left side the heater tap actuall sticks out through the bulkhead. To remedy this I found a different tap (F10 I think) that doubled back instead putting the hose inside the car. In this pic you can see the original 510 tap at the top. The left hand end attaches to the heater and the right goes out through the bulkhead. The tap below is the new one fitted to the 510 bracket (just requires bending the mounting tabs back)
