Anyone else have any troubles disconnecting the fuel hose from the fuel pump mounted on the tank? It has a little quick disconnect like coupling and seems it should just pop right off, but I couldn't get mine to unlatch at all. I noticed the manual says not to use any tools to unlatch the coupling and to only use your hands. Are they afraid of people breaking the coupling or something? I know this sounds like a silly question but this thing was driving me nuts earlier today trying to get it to disconnect. Any help is appreciated. Thanks.
