easy solution to hard start

This same thing happend to my recently purchased 99 silverado... the problem is the fuel pressure regulator.... the regulator is on the driver's side of the engine near the back, right above the cylinders, i believe it is at the beginning of the fuel rail.... it just looks like a round thing bolted to the engine with a rubber hose attached to it.... supposidly there are little tiny holes in the diaphram that is inside this regulator, and these tiny holes are allowing fuel and/or air to escape when it is not suppost to... but when it sits overnight this fuel evaporates and you are able to start just fine... the regulator costs anywhere from $50-$100.... i dont know what it takes to replace it though.... my assumption is that it would not be too difficult to do yourself... let me know how this turns out....
