Whether it’s leaking or damaged, our skilled technicians can transform that old corroded fuel tank to new again both inside and out. Choose Diamond Radiator Ltd. for professional gas tank repair in Langley, the Lower Mainland, and the Fraser Valley. We first give the tanks an acid bath to flush out any rust and debris and then an optional coating is applied to the inside to prevent any further corrosion. We repair steel and aluminum fuel tanks. No worries if you require a custom-sized tank, we can manufacture those too!
