When to change fuel filter when fuel pressure is low?
Dirty fuel filter is the most common issue we see when fuel rail pressure is low. The filter should be changed in the 8,000-10,000 mile range if good fuel is being purchased and running mostly low HP tuning, much sooner if running competition/race style tuning. When in doubt, change the filter!
