Removing fuel from a 2003 Grand Caravan's gas tank can be done in several ways. One method is to disconnect at the rail and jumper the fuel pump relay, as the anti-siphon valve may block attempts to drain fuel through a hose in the tank. Another method is to twist off the gas cap, locate the Schrader valve on the fuel rail, connect a fuel pressure release hose to the valve, and let the fuel drain into a pan. Alternatively, one can try siphoning the fuel using a hose, ensuring the outer end is lower than the fuel tank.
