The importance of a semi-truck fuel tank is one of those things that doesn't need much explaining. A leak can be disastrous and expensive, and replacing your fuel tank is one of those endeavors that's less about improving the look of a rig than it is about making sure it runs properly.
That's why the industry has moved almost exclusively toward aluminum fuel tanks, which are resistant to corrosion and less likely to crack or puncture.
Unfortunately, aluminum fuel tanks can set you back a hefty amount when purchased directly from a dealership. That's why 4-State manufactures our own heavy truck fuel tanks, compatible with nearly all makes and models, and for less than half the price of an OEM semi-truck fuel tank.
