What is a FASS No-Drop Kit?
Jake H • December 8, 2025

If you’ve been researching FASS Diesel Fuel Systems, you’ve probably seen the term “No-Drop Kit” and wondered what it means. Simply put, a FASS No-Drop Kit is an installation option that makes adding a FASS Fuel System faster, easier, and cleaner — because you don’t have to remove or “drop” your fuel tank to install it.

Instead, every FASS No-Drop Kit includes the FASS Single-Bolt Fuel Sump, which allows fuel to be drawn directly from the bottom of the tank — saving hours of installation time and providing a consistent, reliable fuel supply.

Why FASS Developed the No-Drop Kit

Dropping a fuel tank can be one of the most time-consuming steps in a traditional fuel system installation. It often requires multiple people, specialized equipment, and plenty of patience — especially on trucks with large aftermarket tanks or corrosion.

FASS developed the No-Drop Kit to simplify that process. By including a Single-Bolt Fuel Sump (SK5501) with each No-Drop package, you can install your system without ever lowering the tank.

This innovative sump design only requires a single drilled hole in the bottom of the tank, providing:

  • Direct fuel access at the tank’s lowest point
  • Quicker installation with fewer steps
  • Leak-free operation with a secure o-ring seal
  • Clean, professional results without tank removal

What’s Included in a FASS No-Drop Kit

Each FASS No-Drop Kit includes:

  • The selected Titanium Signature Series or Titanium Signature Series PLUS Fuel System
  • The FASS Single-Bolt Fuel Sump Kit (SK5501) for simple tank-side installation
  • All necessary fittings, lines, and hardware for a complete setup

That means everything you need to upgrade your fuel system—without the headache of tank removal.

Available in Multiple Versions

Just like our other systems, the No-Drop Kits come in two versions to match your preferences:

  • No-Drop Kit (Standard): Includes the traditional brass pipe thread fittings found on the Titanium Signature Series.
  • No-Drop PLUS Kit: Upgrades to black O-ring boss (ORB) fittings, offering a sleeker look and enhanced sealing performance.

Both versions deliver the same legendary FASS filtration, air/vapor separation, and reliability — the difference is simply in the hardware finish and fittings.

Why Choose a FASS No-Drop Kit

Whether you’re a professional installer or a weekend DIYer, the No-Drop Kit makes installation faster, safer, and more convenient. And because it uses a bottom-draw sump, it ensures steady, unrestricted fuel flow even at low tank levels — perfect for towing, performance, and daily use alike.


Benefits include:

  • No fuel tank removal required
  • Easier installation with fewer tools
  • Consistent fuel delivery under all conditions
  • Clean appearance with minimal modifications

The Bottom Line

A FASS No-Drop Kit is simply a Titanium Signature Series Fuel System that includes the Single-Bolt Fuel Sump for a faster, tank-free installation. It’s the ideal solution for diesel owners who want premium fuel filtration and performance—without the extra hassle.

Whether you drive a Cummins, Powerstroke, or Duramax, the No-Drop Kit makes upgrading your fuel system cleaner, quicker, and smarter.
