*IMPORTANT – These are 5.9L tubes, not 6.7L*

Brand new set of 6 connector tubes with o-rings for the Common Rail Cummins.

Part Number: DDPJ01572-SET

Notes

Cummins and Chrysler have superseded all of their part numbers for a 5.9L connector tube over to a 6.7L tube. The issue with this is that the 6.7L connector tube has a higher likelihood of leaking compared to the 5.9L tube. For this reason, DDP still sells 5.9L tubes to ensure you have a trouble-free injector install.

Many also believe they will see a performance increase when switching from a 5.9L connector tube to a 6.7L tube. Although this may be true for some, we haven’t seen any gain under the 1,000 RWHP level. So long and short is that if you are planning to stay under the 1,000 RWHP level then just stick with the tried and true 5.9L connector tubes.
