We have been sending midsumps to Australia, USA, Europe and UK for over 2 years now. We do clean and pack them well for their long trip .
Remember, the midsumps are secondhand and some dents in the lower sump can occure.
Most midsumps are not from Turbo engines but for the returnline it is easy to fix a line. More information on Facebook, as a lot of owners have published their solution.
