It all starts with the Diesel. Impurities or water in your diesel fuel can create havoc inside your engine or clog injector systems. Plus, any aftermarket installs you have done that increase your horsepower is not something your factory fuel system can handle resulting in you getting less horsepower than you expected. If you are looking for an upgrade that is easy to install, increases fuel economy, and saves you on a future repair bill look no further.

Save money, time, and your injectors when you upgrade from your stock system to FASS's No Drop Series Fuel System Kit. This all-in-one kit from FASS will improve both diesel pressure and filtration besides being able to run your truck almost to empty before any pressure drops. This kit starts with a Titanium Series fuel system offering advanced filtration that removes water, air, and debris from your diesel fuel at a 2-micron rating.  Plus, with the included easy-to-install sump pump you can rest assured that as long as there is still diesel in the tank your pressure won't drop. Install your FASS kit today; your engine will thank you.

NOTE: Installation of this kit on a cab and chassis may require modifications.

What GPH do I need? This all depends on the horsepower of your truck.

  • 140 GPH- This is for stock up to 500hp.  If you haven't done any aftermarket changes or very minimal ones to increase power this is the one you want.
  • 220 GPH- This is for 500hp to 900hp.
  • 240 GPH- This is for 900hp to 1200hp.

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
