F1C DEF Tank (52022431AM, current)

Replaces 52022431AD, 52022431AE, 52022431AF.

Card-backed ProMaster window: 2014-2016. The big-bill item of the DEF chain ($3,000) - structural damage or crystallization only. The current card lists ProMaster MY2017-2018 rows for this diesel-specific hardware while the documented US diesel window ends MY2016 (Wikipedia + forum consensus 'dropped after 3 years'; one guide extends to 2017) - late-unit VIN-verify advised before ordering.
