HELP PLEASE ! Hi I purchased a DIY little dragon kit a week ago and it was missing the Front Cover and one CLAMP for the WAND . I emailed 4 to 5 days ago but I got no email back. ANY way I managed to make a cover and assembled it to find out that soon as I put the air pressure on the pump LOSES its prime. I checked for leaks and I can't find any . Wondering if the pump is defective.
