So where is the injector pump

O4 2500 do not see any type of pump on the frame between the fuel tank and fuel filter. Any ideas guys.

If you're referring to the lift pump it's mounted to the fuel filter housing. It's on the backside of the housing towards the firewall.
The injector pump is mounted on the driver side of the engine.

The 03s and up use a pump to pressurize a common rail, then use solenoid fired injectors to spray fuel into the chambers.
