mpolli from what I have read in the forum searches the fuel accumulator helps to smooth out pulses caused by the fuel pumps, I think there is a separate system for maintain the fuel pressure after shut off (a oneway check vavle I think) yeah that is what I am going to do is put in the OVP but my wife just called and told me that she had to rev her engine a few time this morning after she started it so boooooo I think I ordered the wrong part.
