Just installed a new ford superduty elec fuel pump.. wich sucks thur a racor fuel filter / water sep.. well install went pretty well now.. starting the truck is a little longer.. cranking time.. i did drain all the fuel rails while doing the fuel pump.. and also the high pressure oil rails.. was wondering. if that could be some of my problem on starting.. (longer cranking time due to air in the lines..) oh.. comming out of the heads i plumbed it to a aeromotive reg.. set to about 62-64lbs pressure.. is that about correct.. do i need a check valve or something.. when i turn off engine my fuel pressure drops to zero.. well thanks for the help
