Quick Ship SKU #: SB-86-3001 S&B Fuel Sending Unit 13-18 and 21-24 Ram 6.7L Cummins

Are you planning on upgrading your stock in-tank lift pump to an external, frame mounted version such as a FASS or AirDog? Because of the fact that your truck has an in-tank lift pump that is part of the basket assembly, you will be required to either install a separate pickup tube that requires drilling a hole in the top of the tank, or an even bigger hole in the bottom of the tank to install a sump. Are you not willing to cut and rearrange most of your fuel tank to keep things running smoothly? S&B's Fuel Sending Unit is the clean and easy way to keep diesel fuel running into your system from a full to an almost empty tank.

Fuel pressure is important to keeping your Cummins engine running smoothly, especially after you have made any upgrades to the fueling demand in your high-performance truck, such as with larger displacement injectors or a performance programmer. If fuel pressure isn't steady or drops off completely, you risk damaging what you spent a good part of a paycheck on. Adding on aftermarket lift pumps is crucial to keeping that fuel pressure as high, as it's needed but they run into the same issues after a tank gets to just a 1/4 full. Any solutions to fix the issue result in a large amount of cutting and adjusting on your fuel tank which adds more points of possible failure and needlessly complicates the entire fuel system. S&B's Fuel Sending Unit has you covered with its venturi jet pump technology, which is designed to keep your lift pump reservoir full even with extremely low levels of fuel in the tank. That means a constant flow of fuel for your lift pump which means a consistent flow of fuel to the entire system.  (It can't help you if you run your truck down to empty though. What were you thinking!?!) Plus, the installation is clean and keeps most of the factory specifications so you spend less time cutting and adjusting your tank or sending unit. Completely plug-and-play, all you need for this install is a wrench, a screwdriver, and a mallet. Whether you are planning on installing a lift pump or you already have one, the S&B Sending Unit is the perfect partner to ensure everything functions and fits seamlessly....plus looks as clean as factory.

NOTE: These sending units will only work along with aftermarket, externally mounted lift pumps (e.g. FASS, Airdog, etc.)
