1. A system, comprising:
a first tank containing methanol;
a second tank configured to receive a portion of the methanol from the first tank;
a heat exchanger configured to provide heat, from an exhaust gas to the second tank to increase a temperature of the portion of the methanol, in the second tank, to generate vaporized methanol,
wherein the heat exchanger is external with respect to the second tank, and
wherein a pressure of the vaporized methanol causes the vaporized methanol to be provided to an intake system associated with an engine; and
a valve configured to cause a portion of the vaporized methanol, in the second tank, to be provided to the first tank to reduce at least one of a temperature of the vaporized methanol or the pressure of the vaporized methanol.
