came across a pump i havent seen before. #402 736 912. stock on a 97 180 hp dodge a/t truck. was expecting a 911 pump . truck also has an egr. havent ran into that in utah before. anyone know anything about this pump? thanks.

 

likely Cali spec, suspect it because of the EGR.

 

912 is the California pump, but I'm not sure whats all different in it.

 

thanks for reply,s. like to know specific pump differences, if any?
