VP44 Medium Duty in Dodge Pickup?

Recommended Posts

I see IPVR16X injection pumps, and they say they fit only cab-chassis and medium duty trucks.  Is this a 'physically won't fit', or a 'emission laws say they can't be used in pickups' statement?
It seems to me that if you're going to put in RV275 injectors or larger, you may as well put in the VP44 model that was DESIGNED for those injectors!  Of course the ECM, cam grind, etc. won't be similarly modified.

A Duck Duck Go search has failed me, so I am now here inquiring.  Blue Chip Diesel and Oregon Fuel injection mention them but say "medium duty only".

Just wondering, I'm not really in the market for an injection pump right now.  [Knocks on wood]

The "029" or 16x will work in the dodge application.  Calibration and parts are very similar.  Some trucks will not be happy with the change and may throw codes.  


Easier to get away with it on trucks that are modded with injectors and programmer, but the codes don't happen a lot of the time.


We will take a 029 core in place of a 027 core.  They are very similar.
