If your truck has the V shaped crossmember connected to the carrier-bearing crossmember(see important note in instructions), the S&B Tank will not fit with this in place.
S&B Sump Fittings/Drain Plug fittings are required when using our sump feed/return port or after drilling out the bottom port to use as a drain. Fittings are under related products.
Do you have an Auxiliary Fuel Tank? using these with our tanks will void the Lifetime Warranty.
