I'm still on my stock pump ,I use additive power service,,139k ,also have a fass,lift ,I've never taken it off ,what is the port you refer to a return,and should I even check it,...blessings

You could check it for peace of mind, it is the fuel return port, as I show in the video, you remove the banjo bolt with a 17mm wrench, if it is 2003 and newer Cummins.

what are you doing with that cpn5 on the bench??

[@MotorsportDiesel]

I thought about adapting a CR 5.9/6.7 to use it. It is an R340, so roughly the same output as 3 CP3 pumps. It's actual reason for being there is that I am building a customer a pump test bench to run some big pumps, this one of the ones he wants to be able to test.

Motorsport Diesel i have a kit to use that pump, information on it is few and far between though. would love to hear more info on it if you have any
