I think for now I will just put it all back as it came off and perhaps change it at a later date.
It does keep the pump away from the elements and the exhaust heat afterall.
I've thrown it all together to show how it was assembled.
The bottom is towards the front of the car.
Pipe comes in topleft to pump and out bottom right.
I'm going to clean it and paint it with POR 15 Chassis black to match up with the rest of the underside.
I may have to modify it slightly though to ensure it clears the H/B cable.
