I have seen where a duramax cp3 is the same as cummins ; is that true ? The reeason I ask is I found a new duramax CP3 for $500.00

One other thing I would like to find all the info I can find on the CP3 injection pump.Would like to learn all the ins and outs how it works and what makes it tick. Done a fair amount of reserch online without much results

Thanks in advance my new found

 

Welcome


Probably not what you are looking for bud some useful info - have a look here:

The only difference between the Cummins CP3 and the DMAX CP3 is the flow port on the metering valve. The DMAX port is rectangular and the Cummins port is triangular.

 

So, the Dmax CP3 will potentially flow more?

 

Thanks guys ; so I guess I need to make the deal on the pump , I have been thinking of going dual cp3 any way. One other thing I have alot of experince with hydrolics ,,,High pressure,, why can't we hook a gauge in the discharge port of the pump to check it ? seems logical to me , just my two cents worth

 

In theory yes, but we need an expert CP3 builder to verify that. The shape of the port is designed more for low flow rate metering. At WOT they should be about the same.
