Narrative:

On oct/sat/01 at XA00 local one hour into a cross country flight from ZZZ airport to ZZZ1 airport. In a small aircraft with no electrical system. A fuel crossfeed valve, located inside the cockpit, fwd of the copilot seat, started dripping. A decision was made to land at ZZZ2 airport, which was closer than ZZZ1 airport. After changing course, the valve, in short period of time, went from a drip to major leak, despite my friend's efforts to contain the leak with paper towels and rags, he was being drenched with fuel. While the drip changed from a drip to a leak I had changed course for ZZZ2 airport, to ZZZ3 airport, to ZZZ4 airport, to ZZZ5 airport, and then finally to ZZZ6 military airbase. I really didn't want to land at ZZZ6, but I knew that the auxiliary fuel tank was full, with six gals of fuel, and that if we were to catch on fire, the airplane would probably burn pretty fast. After we landed I was issued a citation from the military for landing on their property. We later learned that the valve seal failed due to disuse and dryrot over the years. Because I was busy finding places to land and fly the airplane I didn't have time to radio ZZZ6 military base in order to let them know about my situation, and that I needed to use their auxiliary runway.
