My dad just bought a 98 Freightliner dumptruck with a 12v cummins. I read about changing fuel plates and adjusting springs and screws on the pump to get some more power. Just wondering if this all would work the same for this motor? I have a turbo off my 06 to posibly put on it too. Motor has 173k. thanks

 

Get some gauges. Can't add too much power to a working truck. 12v's get hot in a pickup, nevermind a class 6 truck. inline pump or rotary? Inline, I imagine.
