I remember some of the older Detroit engines had an issue where, if the fuel system was not primed through a specific quick-disconnect fitting after service, the fuel pump could be damaged or destroyed from running dry.

It is a 2016 Freightliner Cascadia. It is a one time thing on startup. No loss of power when driving, it is really precise always 1 min to 1 min 30 sec only one dip. No fault codes.
