The Widest-Fitting Kit in the Lineup — 1.5-Inch Gravity Feed
One kit, three brands. The 1.5-inch fill neck is the most common size across Ford Super Duty, late-model Chevy/GMC HD and earlier RAM diesels, and this Southern Truck kit is built for it. Splice the aluminum tee into the factory filler hose and your in-bed transfer tank gravity-feeds the OEM tank.
Key Value Highlight
This is the kit most Super Duty owners need, and it covers a long production run — Ford from 1999 all the way through 2023. No pump, no wiring, no switches to complicate the day. Hoses, clamps, hardware and the shut-off valve are all in the box, and most installs finish inside an hour. Leave the valve closed on the road, open it when you want to top off, and stretch a full day of work between fuel stops.
Features
- ✓ 1.50-inch OD aluminum tee for the common 1.5-inch filler neck
- ✓ Broadest vehicle coverage of the three Southern Truck kits
- ✓ All hoses, clamps and mounting hardware included
- ✓ Shut-off valve included — works with a 3/8-inch female pipe thread tank drain fitting
- ✓ No pump, wiring or switches required
- ✓ Some trimming of the OEM fuel filler hose may be required
Fits
- ✓ 1999-2023 Ford F-250 Super Duty
- ✓ 1999-2023 Ford F-350 Super Duty
- ✓ 2011-2023 Chevrolet Silverado 2500 / 3500
- ✓ 2011-2023 GMC Sierra 2500 / 3500 HD
- ✓ 1999-2012 RAM 2500 / 3500
Does not fit Cab & Chassis models. RAM coverage ends at 2012 — 2013 and newer RAM 2500/3500 needs the 1.75-inch kit, SUT-11408. Diesel fuel only — never use this kit with gasoline or any other flammable fuel.
Benefits Recap
Built for contractors and fleet trucks that live on the road. If your filler neck measures 1.5 inches, this is your kit — and it covers more trucks than anything else in the line.
Measure Your Filler Neck Before You Order — We Will Help You Match It
Older Chevy/GMC HD trucks take the 2-inch kit; 2013-plus RAM takes the 1.75-inch. Call (888) 535-0504 and we will confirm the right size for your truck.
