Review on πŸš€ Airdog A6SPBC259 Fuel Lift Pump for 2001-2010 Chevy Duramax: Ii-4G, Df-100-4G Review by Muhammad Balding

Revainrating 5 out of 5

Removing the standard fuel line is a bit difficult

The air lift pump assembly solved my problem with low suction vacuum at the injection pump. It was a poor design on the part of GM as it didn't have a booster pump to direct fuel into the pump-injector bath. On my first ride in my Duramax for about 250 miles, I averaged 20 mpg while cruising at 75 mph with no load. Easy installation except you take a diesel bath and at the same time cut off the fuel supply to the fuel cooler. The wiring harness is very long, but I just rolled it up in the engine bay and zipped it up.

Pros
  • Everything is great!
Cons
  • Style 90
