Hi Rajul, Glad to here you got your money back. I wasted alot of precious flying time screwing with those fuelers. I see guys fueling there planes with them all the time and I also chuckle when I see the fuel running out of the cowling. I guess they don't care. I personally don't like leaving fuel stains where Ive been.
Take care and remember, altitude is your friend, just like me.
