Auxiliary Fuel Pump Relay
Overview
|
The AFPR is a "Smart" Auxiliary Fuel Pump Relay. This device allows the pilot to flip one switch and quickly drain the contents of the auxiliary fuel tank without over stressing the auxiliary fuel pump. The AFPR will pump down the auxiliary fuel tank, and then automatically shut the fuel pump off when no fuel is detected. The AFPR optionally includes a very reliable optical fuel sensor that can be easily installed in the auxiliary fuel tank or in the fuel line. The AFPR can be operated in and one of four modes of operation. The AFPR also has an output that can be used for a light to indicate when the fuel pump-down has been completed. EASY INSTALLATION |

Reviews
Installed and tested! Installation instructions are easy to follow and the device works as advertised. I installed the sensor in a T-fitting between the pump and the main tank. The device has about a 4 second delay between sensing no fuel and shutting down which works well for my application.
