S&B 40 Gallon High-Capacity After-Axle Fuel Tank (10-1040) for 1994-1997 Ford OBS Powerstroke Trucks

Replacement Fuel Tank for Ford OBS Powerstroke Trucks

The S&B 40 Gallon High-Capacity After-Axle Fuel Tank 10-1040 replaces the factory 13-gallon tank on select Ford OBS diesel trucks. It fits 1994-1997 Ford F-250 models and 1995-1997 Ford F-350 models equipped with the 7.3L Powerstroke engine.

This replacement provides 40 gallons of fuel capacity in an after-axle tank design. Therefore, owners receive more than three times the capacity of the original 13-gallon tank. The added capacity allows the truck to carry 27 more gallons of diesel fuel.

Three Times the Factory Fuel Capacity

S&B designed this replacement tank to maximize fuel capacity on older Ford Powerstroke trucks. Its 40-gallon capacity provides a significant increase over the original tank without requiring special modifications.

As a result, drivers can carry more diesel fuel before stopping to refill. This added capacity can benefit owners who regularly travel longer distances or operate their trucks where fuel stops are limited.
