FASS Drop-In Series Fuel System for 2017 to 2026 Ford 6.7L Powerstroke

Please Note: If you have a S&B or Titan Fuel Tank, you will need to select "TANK" and select "S&B OR TITAN TANK" above.

Please Note: THIS IS NOT A LIFT PUMP! This is an air separation/filtration system that utilizes your factory lift pump.

Please Note: Installation of this kit on a cab and chassis may require modifications. Drop-In Fuel Systems are a plug-and-play filtration upgrade and are not compatible with our Fuel Sump Kit. This plug-and-play filtration system retains the Powerstroke OEM in-tank fuel pump.

The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most effective filtration solution for the Ford 6.7L Powerstroke. Backed by our limited lifetime warranty, the Drop-In Series Fuel System protects your Ford 6.7L Powerstroke from the issues caused by fuel contamination.

If you drive a Ford with a Powerstroke diesel engine and want better fuel filtration, improved reliability, and injector protection without adding an external frame-mounted pump, the FASS Drop-In Series Fuel System is the perfect solution.

Designed as a direct replacement for the factory engine fuel filter, the Drop-In Series delivers cleaner fuel, better water separation, and consistent fuel supply while retaining a factory-style installation.
