At a AROC convention many years ago, Brad Warner, a Bosch guy with
Alfa experience recommended using a hand-operated vacuum pump to
bleed off fuel pressure before opening up a fuel line. Just
disconnect the vac. hose going to the engine fuel pressure
regulator, connect the hand-op vac pump to the pressure reg, and
operate the hand pump. If the press. reg is working correctly, this will
cause fuel pressure to bleed back into the tank.
