    Just wondering if you can disconnect DEF tank inlet hose to pump/filter, and disconnect DEF doser attached to 1 box. And run a inlet line from pump/filter to bucket of hot/warm water. Use software (my case Detroit dddl 8.13) and run the quantity test 1 to several times to clean entire system of def crystals. Maybe even use ionized or RO water. And allow to sit a bit in between times running quantity test to allow crystals to desolve. Then run good DEF to flush out water. Cost a filter and copper seal at doser/1 box.
    Reset any codes, if applicable, caused by process.

    If not able to run quantity test through software maybe run appropriate direct voltage to pump to activate.

    Every body knows DEF is a money pit, corruption at it best, politicians passing laws for $$$$ and corporations producing DEF are becoming billionaires forcing other to use their products, this is not capitalism anymore, we are living under communist corruption, the best solution for DEF is = get that stinky fluid out of our life, there is not a single truckers out there who likes that stinky good for nothing fluid in their trucks, is not about the environment, is all about $$$$$ and corruption.
