Whether you're running through dusty fields with a chisel plow or tedding hay on a windy day, this filter keeps your fuel system protected when conditions get tough. Today's high-pressure injection systems need exceptionally clean fuel to deliver the power and efficiency you're counting on. Made to Last Modern diesel injection systems operate at pressures that would make your grandfather's tractor mechanic nervous.

Good to Know Always replace your secondary and primary filters together to keep your fuel system balanced. When you're installing this filter, take a minute to prime the system properly—it'll save you from air-related starting issues later. If you notice this secondary filter getting dirty faster than usual, it's worth checking your primary filter and fuel supply for contamination problems.
