A Diesel truck’s stock tank doesn’t always satisfy the needs of its owner. Aftermarket fuel tanks have been designed in order to meet that demand, and were created to hold roughly double the typical amount that a normal stock fuel tank can, significantly increasing a vehicles range.

These aftermarket tanks are made of very high density and cross linked polyethylene, which gives these tanks about twenty times the resistance to environmental stress cracks. They have a ten times greater molecular weight and five times the impact strength over OEM or Original Engine Manufacturer/stock tanks. This cross-linked polyethylene construction is notable due to its natural chemical resistance; it will not corrode, and is hardly even affected much by high levels of condensation.
