I have a few questions about adding the Kennedy lift pump. I called a couple of diesel shops in my area and asked if they installed a lift pump on my truck, would that help the CP4 to last. Both shops said no. I do have a Nicktane adaptor and use the Donaldson fuel filter plus the Nicktane auxiliary fuel/water filter. Do you guys think the Kennedy lift pump will help the CP4 to last longer? If so, how does it help? Other than the filters, my truck is stock.
