2001-2004 Duramax LB7 S&B 62 Gallon Fuel tank (10-1023)

The 26-gallon OEM tank that came in your Duramax is simply not enough - the S&B 10-1023 bumps your capacity to 62 Gallons with no cutting, drilling, or modifications and installs in under 4 hours. Not only does it over double your carrying capacity, but it also includes a premium OEM-style sending unit and features a built-in sump which can be used for aftermarket lift pump installation, if desired. S&B recommends aftermarket lift pumps be installed according to the pump manufacturer's instructions only. The S&B sump will not cure typical "1/4 tank issues"  common with aftermarket lift pumps
