This dual pump add-on kit can be purchased along with the 20-3790 fuel pump hanger to allow a second pump to be installed into the tank. The fuel pump hanger is required to use this add-on. If a brushless pump is being installed the system is limited to one pump and the dual pump add-on can NOT be used due to the extra brushless controller wires.
The architecture of this Honda fuel tank is very unique. Because the opening is so small, 2 pumps cannot fit through at the same time. Additionally, the angle of insertion combined with the tall collector bowl and shallow tank make dual pump installation rather difficult.
An electrical plug and a SAE quick connector eliminate the need to perform tedious assembly before dropping the entire assembly into the tank. Both fuel pumps merge into the single 8AN ORB outlet of the fuel hat. And because of the integrated check valves with the following pumps, staging is permitted.
