The stock Oil Pressure Sender is designed to turn the light on at about 5psi.
 The VDO Dual Sender is designed to have the light come on at about 7 to
10psi.  If you've got oil pressure that low at idle (should be about 950rpm),
there may be too much clearance on the main/rod/cam bearings - that's been my
experience - could be a tired oil pump too.

Never have had a true reading off the nipple-tee type fitting.  The oil plate
sender is the way to go, however it does not replace the drain plug.  You
have to drill a hole in the 2nd sump plate located just below the filler tube
(as per sender instructions) to mount it there.

Good luck with gettin' the temp :)
