FASS No-Drop Series 220GPH Fuel System for Chevy/GMC (2020-23) 6.6L Duramax (500 - 900hp)

FASS No-Drop Series 220GPH Fuel System for Chevy/GMC 6.6L Duramax (500 - 900hp) Includes TSC15250F220G (250F/220gph/70-75psi) Fuel System + SK5501 FASS Diesel Fuel Sump Kit Please Note: This Fuel System REQUIRES aftermarket tuning to be compatible. Installing a Titanium Signature Series Fuel System has never been easier, or more affordable. Designed to simplify installation, No-Drop Kits include our Fuel Sump—which prevents the need for removing your fuel tank. Better still, No-Drop Kits offer significant savings over buying a Titanium Signature Series Fuel System and Sump Kit separately! These Kits include everything you need for a simple, straightforward FASS installation—and nothing you don’t. Please note: No-Drop Kits are a complete fuel system upgrade that includes a Titanium Signature Series Fuel System and FASS Fuel Sump. Tuning required: For installation on 2017+ L5P Duramax trucks, tuning is required to prevent a check engine light. If you are not tuning your L5P Duramax, please check out our Drop-In Series Fuel Systems—which are plug-and-play filtration upgrades that do not require tuning.
