A 100-lb propane tank can run many portable generators about 20–50+ hours depending on size and load. See runtime estimates, fuel-use tables, and formulas.

A 20-lb propane tank can run a generator about 5–25 hours depending on generator size and load. See real runtime examples, fuel-use tables, and a simple formula.

A propane generator may backfire because of a lean fuel mixture, low propane flow, ignition trouble, incorrect choke use, valve issues, or unburned fuel in the exhaust.

Propane pressure drops when a generator starts because fuel demand rises suddenly. Learn how tank size, regulators, piping, temperature, and restrictions cause pressure loss.

A propane generator that loses power under load usually has a fuel-flow, regulator, tank-vaporization, air, ignition, or overload problem. Learn what to check.

Quick Answer: If your propane generator surges or hunts—meaning the engine repeatedly speeds up and slows down—I usually look for an unstable air-fuel mixture or unstable governor response. On propane, common causes include low or fluctuating fuel pressure, a restricted or undersized regulator or hose, a sticking demand regulator, low tank vaporization, air leaks, incorrect

Quick Answer: If your dual-fuel generator runs normally on gasoline but will not start on propane, I focus on the propane side of the fuel system. The most common causes are an empty or weak propane cylinder, a cylinder valve that is closed or not fully open, an incorrectly connected regulator hose, the wrong fuel-selector
