Having ruled out hoses, a filter and the motor, Norbu keeps taking pieces off until we find the source of the problem. Our manual has been misplaced...? In any case, David Anderson (foreground) lent us some of his tools (he's doing work on a house on the property) and watched the process for a while. Eventually, Norbu did remove that large metal piece on the bottom, which connects to the intake hose. Sure enough, it was clogged. Gabriel cleaned it out with water, and we put it all back together. Despite Gabriel's initial doubts, it worked! The Titan is back up and running!
