I use this for my 5hp Honda outboard. Fits between the back seat and transom very nicely. Only problem that I have had is that if I fill it my engine stalls. Not sure why the fuel does not feed well onto the engine when full, but it doesn't. Yes, the gas cap air valve is open. I keep about 2 gallons of gas in this tank instead of 3 and then I have no problems.
