Ford? F250 F350 F450 F550 Super Duty Series "Diesel Only" 40 gallon rear truck tank. This tank replaces the 6 Bolt style sending unit, not the lock ring style. This tank does NOT include sending unit, sending unit gasket, EMS valve or EMS valve gasket, but includes 6 new bolts and thread sealer for the sending unit.
Because of the gasket location on this tank, thread sealant must be used on all 6 bolts and a new OEM gasket should be installed with the sending unit. The sending unit hole is approximately 4 ?" wide.
