AirDog Electric Fuel Pumps A4SPBD004 Editorial Review
The AirDog (A4SPBD004) Fuel Air Separation System is a popular choice for truck owners looking to improve fuel efficiency and performance. Designed specifically for the 1998.5-2004 VP44 and early CP3 Cummins engines, this fuel system mounts to the frame rail using a supplied sandwich plate mounting system. It features a 150GPH flow rate and connects directly to the VP44 or CP3 injection pump, bypassing the factory fuel filter housing. The system also includes an Air/Vapor return that is sent back to the tank through a filler neck tee. Customers have reported positive results after installing the AirDog Fuel Air Separation System. Many have noted improved fuel economy, smoother engine performance, and faster spooling. Some customers have also appreciated the ease of installation, with one reviewer mentioning that the single line running to the front cleaned up the engine compartment nicely. The system has also received praise for its quick delivery and the inclusion of almost everything needed to complete the installation. There have been a few issues raised by customers, notably regarding the noise level of the pump. Some reviewers have found the pump to be quite loud, making it difficult to hear the engine over the noise. However, the customer service provided by AirDog has been highly regarded, with one reviewer mentioning that their customer service representative went above and beyond to rectify an issue with a faulty product. Overall, the AirDog (A4SPBD004) Fuel Air Separation System has been well-received by customers who have experienced improved fuel efficiency, smoother engine performance, and easy installation. While there have been some noise-related concerns, the positive feedback on customer service has helped to maintain a positive reputation for the brand.
