The fuel filter in a Cummins engine should be replaced every 5,000 miles, or every oil change. Some people change their filter every 10,000-15,000 miles, but this is not recommended. The replacement of both fuel filters is an easy DIY project that should take no more than 30 minutes to complete.

The rear filter should be changed every 15,000 miles, while the front filter can be changed every 30,000 miles
The rear fuel filter on a Cummins engine should be changed every 15,000 miles, while the front filter can be changed every 30,000 miles. This is because the rear filter does a good job of extending the life of the front filter.
Some people prefer to change their fuel filters more often, such as every 5,000 miles or every oil change. This is because the filter only costs around $15, and it's better to be safe than sorry. However, others argue that the rear filter can be changed less often than the front, as it is less likely to get clogged up.
One way to know when to change your fuel filter is to install a fuel pressure gauge after the fuel filter. This will indicate when the filter is plugged and needs to be replaced.
Changing both fuel filters is an easy DIY project that should take no more than 30 minutes to complete. You can order the filters online for around $100 for both.

Some people change their filter every oil change, which is around every 5,000 miles
Some people change their Cummins fuel filter every oil change, which is around every 5,000 miles. This is a relatively frequent interval for changing the filter, as others have reported changing their filter every 10,000 to 15,000 miles or even every 30,000 miles. However, those who change their filter more frequently may be doing so as a preventative measure to avoid any potential issues with their fuel system and engine. Additionally, the cost of the filter is relatively low, typically around $15, which makes it more feasible to change the filter more often.
Changing the fuel filter is generally considered to be an easy do-it-yourself project that should take no more than 30 minutes to complete. When changing the filter, it is important to use a ziplock bag on the rear filter to avoid getting doused with diesel fuel. Some people also choose to install a fuel pressure gauge after the fuel filter as an indicator of when the filter needs to be changed. However, it is worth noting that even with a fuel pressure gauge, it can be difficult to determine exactly how often the filter needs to be changed, as this can vary depending on various factors.

A fuel pressure gauge can be installed after the fuel filter to indicate when it needs to be changed
The fuel pressure gauge will help you to monitor the fuel pressure and identify when the filter needs to be changed. This is a more accurate way of determining when to change the filter, rather than simply relying on mileage. It is also a good way to identify any other issues that may be causing a drop in fuel pressure.
