Optimize Fuel Efficiency with AirDog (A4SPBD005) Fuel Air Separation System Review

So the pump itself works great, I have 50hp Smarty Touch on 9 injectors with max timing, valair clutch etc. The pump works fine the only problem is the loud noise . It wouldn't be so bad if the wiring harness was long enough to mount in the back, but it's long enough to get behind the back seat. In short, turn on the radio and drive with confidence.

Airdog looks great and feels solid. However, after installing it, I realized that they sent me the wrong year 2005. The unit should be the same but the seat belt doesn't fit my 2001 model. All I need is the right seat belt and it will be 5 stars. Just take a look. I called people at AD, they said a new part was on the way. Arrived on Friday as promised. Installed, everything works, my truck works again.

First of all, this is not a 4G pump. For the price you can tell but they never state in the description. Second, my wiring harness adapter plug that goes from the factory wiring harness to the new pump was not properly connected. Huge ass pain trying to solve problems. I had to drain the tank a second time to find out. I tried to access airdog but to no avail. I really like the pump, there are no problems with the seller and delivery. I only wish Airdog had better quality control and customer…
