And if you connect the muffler pressure tube to a small container you will save fuel ( $$$$ ) and not get it in your eyes. I use an extra hunk of fuel line and pump the excess back into my fuel can. I use a small clear plastic connector between the muffler tube and the fuel tube to the can so I can see when the tank is full. Probably only get about 3 or 4 extra flights a year but the ground LOVE's it. ENJOY !!! RED
