Is your Ford Super Duty suffering from the Ford fuel tank delamination problem? If so, order this 2011-2015 Ford F350-F550 Super Duty Series “Diesel Only” 40 gallon rear polyethylene fuel tank. This tank does NOT include sending unit, an EMS valve, EMS valve gasket, straps or skid-plate.
Each tank includes a specifically designed sending unit gasket (4740L-OR), 7 new bolts/washers, a tube of thread sealer & EMS valve plate with 6 bolts. Sending unit opening is approximately 4 5/8″ in diameter. When installing the original sending unit, make sure the fuel bowl sits properly in the bottom of the tank and use the original lock ring to hold the sending unit in place with the provided seven bolts (See bolt pattern image). Make sure to coat each bolt with the thread sealant. Do NOT use the OEM sending unit gasket.
If you have a 6.7L diesel engine, you may have a larger diameter sending unit, so please measure before you purchase this tank. Some 6.7L sending units had metal tank with a 5 1/8″ opening and a 5″ diameter sending unit. If necessary, the sending unit opening in this tank can be trimmed out to 5″ using a fine tooth saber saw blade. The tank’s bolt pattern and inside fuel bowl depth will accommodate the larger sending unit.
This diesel only poly tank will directly replace your existing tank that was damaged due to delamination. It fits 2010, 2011, 2012, 2013, 2014, 2015 Ford F350, F450, F550 Super Duty pickups.
