Did you make the same mistake I made and buy the kit off E-Bay? I did and had the same problems they are using a high volume pump from a French Block designed to be used on motors that ran pumps, generators etc. My oil pressure was all over the place at engine speeds that made no sense. I pulled it out and used the correct kit that Phil from Gollers Hot Rods in Michigan. 419-428-2271. Phil is a really nice guy and very helpful. His pumps are not on E-Bay because he wants to talk to the person doing the installs to ensure they are being installed correct. The line from the pump out the pan is indexed to help you get a visual refernce so you do not kink the hose. He uses a Melling std pressure pump made in the good ol USA. It works good for me now...15lbs pressure hot at idle and 60lbs hot at 4,000 rpms. Clean filtered oil which would have saved my motor las summer when a valve spring broke and ran through my motor taking out an NOS 4" crank.
