Cummins PT Pump
PT Pumps are available. Most pumps are for sale at about $200, Cummins sells a rebuilt pump for about $450.
These pumps are not difficult to reseal/repair. Ordinarily the pumps need little service unless some engine changes happen. One basic change in a pump is more power wanted. Any upgrade in the turbo sometimes requires a pump change. With little knowledge, the engine will make lots of smoke and not much more power. Changing a pump from one engine that the same, requires no pump work. Economy is mostly controlled by the driver. Few truck shops
work on old engines. Frank
