We just bought another Rollback for our company. It has the 8.3L cummins with a fuel pump that looks like the P7100 just on a little larger scale. I was wondering if this has the same type of fuel plate. We want to turn it up some to give it a little more power. We currently have a International 9400 with a Detroit 11.1L series 60. So, replacing it with this smaller cummins we want some more power out of cummins than stock. It is a peterbuilt. Thanks for any help in advance.

Come on guys! I know someone out there has experience with these. Can you just turn up the pump like the 2nd gen 12 valves?
