Injection Pump

The Roosa-Master injection pump is mounted on top of engine, beneath the air crossover. This pump is cam driven and delivers fuel to the injectors at 1800-2000 psi. See Fig. 1  .

Driven at camshaft speed, the rotary pump can precisely govern time and amount of fuel injection. Eight equal-length pipes, running from pump to injectors at each cylinder, ensure that injection timing does not vary from cylinder to cylinder.
