Hi everyone I am haveing a big dilemma I would like to know what you all think about lift pumps airdog or Fass which one would you prefer
 
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
