be dangerous. Explosion or fire may cause death or serious injury.
Always properly steam clean a fuel tank before repairing it.

serious injuries or death and damage. Fuel can also irritate skin and
eyes. To prevent this, do not damage the sealing surface of the fuel
pump unit when removing or installing.

explosion, resulting in death or serious injury. Before draining fuel,
