What kind of pump does an ISC engine have?
The original ISC engine featured a Cummins Accumulator Pump System (CAPS). This CAPS pump was a computer controlled injection pump,with individual fuel lines to each injector. In 2003 the HPCR system was introduced.
What’s the difference between ISB and caps pump?
ISB came with the infamous electric lift pump and the VP-44. ISC came with the same infamous electric lift pump, and the equally infamous CAPS pump. The ISC lift pump also had a built in bypass and only ran for 2 minutes at engine start it was then turned off and the CAPS gear pump then pulled fuel from the tank through the bypass.
What happens if caps fuel injector pump fails?

How often do you change an ISC 8.3 L engine?
The big engineering feat of the Cummins ISC 8.3 L was the ability to over-lubricate the engine and reduce the possibility of thrown rods or spun bearings. The frequency of oil changes was examined and then designed to dramatically reduce them to, on average, once every 15,000 miles.
When did Cummins start using the ISC engine?
Beginning in 1998, Cummins introduced the ISC based off the earlier mechanical 8.3 C-series engine. The original ISC engine featured a Cummins Accumulator Pump System (CAPS).
Where are the fuel filters located on a 2000 Cummins ISC?
The early 2000 Cummins ISC engines only had one fuel filter – positioned AFTER the lift pump. Consequently, any foreign material that was pumped from the fuel tank went through the lift pump before it was filtered. The number of fuel filters is determined by the chassis manufacturer.
