I have never really understood the process of going to the nicktane filter adapter or why people do it when they have a lift pump.
Maybe im just dumb, but I have a kennedy lift pump and feel like I will just mess up something deleting the filter head or going to the adapter
I switched to Nicktane and a Donladson P553203 W/S filter (specifications are close to the OEM type except much higher GPH), by removing the check ball per Nicktane directions, opening up where the ball seats and the Donaldson flowing at 90GPH as opposed to 45GPH for the OEM type my truck no longer starves or drains the rails without a lift pump. With that said the guy that scripted my tune said I could "get more sideways with a lift pump....:woott:"
