Neither. Mechanical belt drive would be my preference. Dodge example below, but, you get the idea.

Another idea is the: Kennedy Diesel Duramax "flow on fail" lift pump. Google it. No link - not a vendor and other vendors sell competing products.

GDP pump for reference as no vendor sells anything like it that I am aware of.

The belt driven pump is beyond overkill for a basically stock truck, and is introducing something else to fail imo. Airdog and fass are about neck and neck anymore. I run a kennedy single pump on mine because the cp3 on a duramax needs volume, not pressure to it since it already has a gear driven supply pump on the cp3. AFE has a new lift pump that has gotten good reviews. Depending on where you live/travel, make sure you get one with a fuel heater if you will go where it gets colder than freezing
