Which FASS Fuel System do you need for your 6.7 Powerstroke? Compare the Drop-In Series, Titanium Signature Series, PLUS, and No-Drop options in this quick article!

The 6.4L Powerstroke (2008–2010) is a strong, powerful diesel platform—but like all high-pressure common-rail engines, it depends heavily on clean, consistent, air-free fuel to stay reliable. Injectors and fuel system components on the 6.4 Powerstroke are especially sensitive to contamination, making fuel filtration one of the smartest upgrades you can make. FASS Diesel Fuel Systems offers several proven options for the 6.4 Powerstroke , including the Titanium Signature Series, No-Drop, and PLUS variants. This guide will help you quickly understand the differences and choose the right setup for your truck. Choosing the Right Flow Rate (GPH) Choosing the right Gallon-Per-Hour (GPH) or flow rate for your 6.4 Powerstroke's fuel system is a crucial but easy step. The more power your truck makes, the higher GPH system (more fuel) you'll need. Here at FASS, GPH ratings for our 6.4 Powerstroke Fuel Systems break down like this: Stock to 600hp: 100GPH 600hp to 1,000hp: 165GPH 900hp to 1,200hp: 250GPH 1,200hp to 1,500hp: 290GPH To select the right GPH FASS Fuel System, simply choose the GPH that's rated for the horsepower your truck makes. Please note: If you have performance modifications planned, you can absolutely install a higher-flow (more GPH) FASS Fuel System than you currently need. It will not hurt anything. However, you may notice increased fuel pump noise; due to the higher volume of fuel being moved.
