One fuel tank, two uses. When space is limited having gear that is dual-use is critical. We need and external fuel tank for the generator at base-camp and a spare fuel can for Campbell on excursions.
We use a portable marine fuel tank designed for outboard motors for both. It is very rugged, completely sealed, and fitted with connectors that attach to the generator.
We chose a six-gallon tank, but they come in many sizes. Full, it weights around thirty-six pounds, so we can easily lift it to our roof rack. It has pipe threads to accept a fitting.
It stays with Campbell on excursions, and when we return, we connect it to the generator. When we get a proper swingout rear bumper, we will mount it there.
We have a Generac iQ2000 inverter generator. Depending on the load, it will only run a few hours on the internal tank.
An external tank allows us to run it a long time without pouring in more gas. We use a sealed cap with pipe threads to accept a fitting.
A hose connects the tank to the generator using standard outboard motor connectors. It has a bulb for priming the fuel flow into the generator. Once the generator starts, it will draw fuel into the tank as it runs.
All of the connectors close when the hose is disconnected, so there are no fuel spills. You can find the parts we used in the list below.
We carry an identical hose without the fittings in Campbell. We can use it to transfer fuel from the tank into Campbell on excursions.
Thanks to Ryan Anderson for suggesting we adopt the outboard motor setup.
