An integrated unit pump injector that includes a cam follower, unit pump, injection line and injection nozzle is pre-assembled for installation in an engine block and cylinder head. By pre-assembling the integrated unit pump injector, the assembly can be tested for fuel leaks, injection timing and volume of fuel delivered by the pump without first installing the individual devices in an engine. Variation in fuel output, injection timing and fuel volume is reduced while engine assembly time and cost is also reduced. The integrated unit pump injector orients the pump and nozzle on parallel axes and requires that the pump bore in the block and the nozzle bore in the cylinder head also be parallel to enable the injector and pump to be fixed relative to one another prior to installation and both installed simultaneously by movement in the direction parallel to their axes.
