Can you describe how the new gas cap and hoses work? I'm not following your description very well. I'd like to add more fuel capacity and like your modification of a regular tank
Thanks.
The new Gas Cap is a vented gas cap that is made for the Honda Generator. I remove the vent Hardware (just a cotter pin removal to disassemble), then I tap a hole to screw in the hose adapter.
For the regular gas tank, the purpose of the male and female adapters is just to get a hose to the bottom of the tank so gas can be drawn with no air getting into the line. The hardware just couples the hose through the wall of the tank.
The exterior gas hose just connects the two tanks. The Honda Generator will draw gas through the line as it uses gas. A gas tank normally creates a vacuum as fuel is consumed and must be vented else the gas stops flowing. This setup just allows the vacuum created in the Generator tank to pull gas from the bottom of the auxiliary tank which vents through its own vent. The Honda is creating a syphon action.
The idea is to get the hose connected to the top of the Honda via the modified cap to the bottom of the auxiliary tank. You could just drill a hole in the tank cap that is just barely big enough for the hose to fit and push the hose to the bottom of the tank. That would work without any hardware for the auxiliary tank. You just need to be able to seal the gas tank when the hose is removed.
I hope this helps.
