Combustion tool

A fuel delivery system for a combustion tool, said fuel delivery system comprising:

• a vaporizer including:
• an inlet;
• an outlet;
• a first pressure regulator fluidly connected to the inlet;
• a second pressure regulator fluidly connected to the outlet;
• and
• an evaporator fluidly connected between the first pressure regulator and the second pressure regulator,
• wherein the vaporizer is configured to receive, when in use, fuel from a fuel cartridge on the combustion tool through the inlet so that fuel goes through the first pressure regulator, then through the evaporator, and then through the second pressure regulator so that the fuel is delivered through the outlet at a substantially constant pressure.
