Features

Enjoy a quicker setup while gaining an additional 10 gallons of capacity compared to competitor tanks, letting you save time and fuel on your journeys.

S&B recommends following the pump manufacturer’s instructions for installation. Note that the S&B sump will not resolve typical "1/4 tank issues" often associated with aftermarket lift pumps.

• The distance to empty (DTE) on GM trucks can’t be reprogrammed, so it will show about half the mileage that is really left. This occurs with all aftermarket high-capacity fuel tanks.
• The bottom of the S&B tank has more surface area than the OE, so there will be a greater fuel reserve when the low fuel indicator comes on.
• The nozzle at high-flow fuel stations(truck stops) will not be able to fill automatically.

Note: This fuel tank fits 2001-2004 LB7 trucks only. 2004.5-up trucks with LLY, LBZ, and LMM engines use part # 10-1006.

WARNING For Those Using Auxiliary Fuel Tanks

On S&B and OEM diesel fuel tanks, there are one or more rollover valves. The rollover valve uses a float/weight to close the valve when the float is immersed in fuel. This prevents fuel leakage in the event of a rollover. Gravity feed tanks or electronically controlled feed tanks can overfill the S&B or OEM tank. If/when the tank is overfilled, the rollover valves will prematurely close. Without the required vapor space in the tank, this violates the “overfill restriction” requirement of 49 CFR 393.67(12)(i). An overfilled tank can lead to a pressurized fuel tank, leaking, and tank failure. Therefore, the use of a gravity feed tank or electronically controlled transfer tanks (that allow the S&B tank to overfill) in conjunction with a S&B Tank is dangerous and will void the S&B Tank warranty.
