We had a big windstorm here in Michigan and lost power for a day so our little Honda EU2000i generator got a good workout powering our home furnace, refrigerator, TV and sump pump. We’re glad we had it around since yesterday’s lows were in the single digits. Since I had it out I thought I’d show some pics of our cheapie extended run setup.
To build an extended run rig, I picked up a used Honda gas cap, took out the vent parts then drilled and tapped the cap for a ¼” barb hose fitting. I also got 6 feet of ¼” transparent gas line and a small piece of clear tubing that fits over the gas can vent. All told I think I spent $30 bucks. You can buy aftermarket extended run gas caps for about $35 bucks but you still have to buy the hose and a barb fitting.
To use the kit, I first fill the generator tank pretty full but it doesn’t have to be to the brim. Next, the cap goes on but not snugged down tight just yet.
The other end of the fuel line gets stuffed down the fill spout of my 5 gallon gas can. I push it in far enough so it reaches the bottom of the can.
Now the short piece of clear tubing gets pressed over the gas can vent thingy.
The Honda gennys have fuel pumps in them so the gas can doesn’t have to be elevated. To fill the fuel line and top off the genny’s tank I blow air into the clear tubing on the gas can vent and since the genny's gas cap isn’t on tight the extra air in the tube will vent out the cap and fuel will flow into the genny’s tank. Sometimes a bit of fuel leaks out the cap while I'm priming it but I usually snug it down as soon as I see fuel flowing into the genny’s tank and no fuel gets slopped. If there’s a bit of air left in the tank the fuel pump will still draw fuel out of the gas can.
Now you’ve got 6 gallons of gas, which even at full throttle should last a day or so. In ECO Mode maybe 3 days depending on the load.
When getting ready to shut it down I unscrew the gas can fill spout, pull the tube out of the can and hold it up to let the genny draw the fuel in the line into the tank. If I unscrew the genny tank cap without draining the line, fuel will siphon out of the gas can and soak my new xmas sheepskin slippers. Boo, Hiss.
I love our Honda. It’s very well designed and built, very quiet and easy on the gas. We used about 2 1/2 gallons of gas for nearly a day’s use on ECO Mode (which lets the genny adjust it’s speed to match the load). All-in all, the little buggers are lifesavers.
