AirDog Service Indicator Light

Alright, so you added an AirDog fuel system to your truck, nicely done. You can now rest assured you won't starve your injection pump of fuel. But, how do you know when its time to change the filters to ensure you're feeding your engine clean fuel? Are you just changing them out every 15k? How do you REALLY know that you didn't pick up a bad tank of fuel. You don't, that's the point. With the addition of Pureflow's Service Indicator Light Kit, you won't even need to think about it. This kit will alert you anytime it sees fuel pressure drop below 5 psi, and if it maintains, its time to change the filters. If its a momentary illumination, it might be tim for a bigger pump!
