A fuel system for a fuel injected engine includes a manifold for supplying actuating fluid to a plurality of fuel injectors and an accumulator in fluid communication with the manifold. The accumulator is charged while the engine is running by an actuating fluid pump coupled to the manifold. After the engine has been shut off and a particular engine condition is detected, actuating fluid is supplied to the manifold by the accumulator to fill voids left by contracting actuating fluid.
