Calling on Hank Hill...

We’ve got a standby generator (B&S 7 kW) that runs on propane. It’s about 10 years old and has always been reliable, and has at least 1k hours of run time.

Last couple of times the power went out, it sputtered under light load and after a couple minutes stopped with “low voltage” error code. I think it is not getting sufficient gas flow. The propane tanks (got 3 connected together @ 120 gallons each) show about 20% full. It’s a pretty long run from the tank to the generator, but it’s a 2-stage system with 1.5” pipe from tank to 2nd stage regulator.

Just wondering if the low level in the tanks could cause a lack of flow. Was also thinking it might be good to boost the pressure on the first stage...
