Questions and Answers

Can this warning light system be tied into factory fuel systems?
View Staff Answer 

The PureFlow Technologies Filter Replacement Indicator Light Kit is intended for the AirDog fuel systems only. Check out the “Gauges” section of our site for a complete line of fuel pressure gauges.

will this work with the air dog raptor pump? Fuel low pressure light
View Staff Answer 

The AIRDOG 901-04-0003-3 LOW PRESSURE INDICATOR LIGHT is not designed as a plug and play for use with the Raptor fuel pump. However, you can use the indicator light in conjunction with our XD200 fuel pressure adapter (assuming you already have ½” fuel lines).

Will the AIRDOG 901-04-0003-3 LOW PRESSURE INDICATOR LIGHT work on my 12V 1997 Cummins? My 1997 12V Dodge Ram 2500 is totally stock. I have had lift pump failures in the past on other 12V Cummins motors and would like an indicator if my current truck's lift pump fails.
