WCraigH Posted June 15, 2006 Share Posted June 15, 2006 IMO, the best place would be to "T" off the front of the driver side cylinder head where the outlet for the bypass filter is located. Do NOT plumb it so that the gauge is after the fitting in the head because that is (or should be) a restricted outlet. Instead plumb it so that the restricted (stock) fitting is AFTER the "T", but still goes to the filter (of course). The other side of the "T" goes to the gauge.That particular location is the lowest pressure in the engine. In contract, the pair of outlets next to the distributor (one plugged, one with existing sender) are essentially the highest pressure in the engine and do NOT really tell you what is going on downstream.As far as measured pressure, I would be concerned with any reading below 15psi at hot idle. The max reading should not exceed 50psi and probably will not exceed 40psi on a good used engine. Link to comment Share on other sites More sharing options...
