Got an AirDog fuel system? Be sure to have come extra fuel pressure fittings on hand with the AirDog Fuel Pressure Fittings! Featuring more reliable and accurate fuel pressure readings, owners of the AirDog fuel system can keep a watchful eye using the included fuel pressure tee. This allows the user to install a fuel pressure sensor right at the high pressure fuel pump! Made with a 1/8th NPT, this fitting is a Push Lock style fitting that is made for installing the fuel pressure sensor. Installing the fitting closer towards the engine enables greater accuracy in readings for your diesel fueled truck.
