That's the regulator, and there should be no fuel coming out if it. If there's an internal leak due to a ruptured diaphragm, the extra fuel gets sucked up into the vacuum hose, and eventually makes its way back to the intake manifold, and makes the mixture way too rich. Any clouds of black smoke coming out of the exhaust?
