Very good information. I'd say if you were going to end up in the DRC, stay as west as possible. Closer you get to the east, the danger levels pretty much go up.
Don't have one myself. Stumbled across this online though, not sure if it will help: https:// x8r. co. uk/land-rover-discovery-3-4-range-rover-sport-air-compressor-repair-kit-hitachi-end-cap
All the best.
