1. A system for measuring fuel delivery from a multi-fuel injector of a device, the system comprising:
a fuel injector for injecting a first fuel and a second fuel;
a first fuel pump for supplying the first fuel to the fuel injector;
a first sensor including a first measurement reservoir for measuring a volume of flow of the first fuel to the injector, the first measurement reservoir having a supply chamber that that decreases in volume upon actuation of the fuel injector;
a second fuel pump for supplying the second fuel to the fuel injector; and
a second sensor for measuring a volume of flow of the second fuel to the fuel injector.
