Although very durable, diesel pumps wear slowly over time and a rebuild or replacement is part of a normal service schedule. Add any diesel impurities to the mix, and pump performance becomes compromised often accelerating the rebuild/replacement schedule. If you own any of the following Cummins-powered models, you know how difficult it has become to find new original parts.
