ive got 3 cummins. each one has a different pump. My question is on the injector side of things, are the injectors out of each truck different? If so, can someone tell me the 3 different sizes of injectors please. Sorry if this has been answered, google search helped in no way.

 

5x009.5's on the little pumps and 5x0105 on the 215

dv's are
131 on the 160hp
181's on the 180 and 215 pump

 

good to know .... thanks turbo

 

Are the bigger DV's interchangeable into the older pumps?

Is it a good upgrade or should the injectors be done first?

 

yes, you can also make hybrid DV's using 181's and 131's, but i wouldn't fool with that. 191's or .024's offer a noticeable fueling increase, both before or after an injector swap. it would be your call.
