I have some 2021 Bluebird visions I think they are 6 .7 engines. After I change the fuel filters . How do prime the system before starting the engine ? Most of the cummins I have worked on had some kind of primer

I just fill filters and start and run it at 1200rpm never had an issue, none of our Cummins have a primer from 2010 to the 2021s

All of my Cummins powered units have a black, triangular shaped primer handle on the side of the fuel filter housing. Unscrew the handle to the left, pump the primer as usual, tighten and fire the engine. Otherwise, Bluenozer has the old school way of doing it that works all the time for me too.
