RE: 1988 Ram 318 Oil Pressure Sending unit
Well, as far as the '88 model is concerned, I couldn't tell you. However, on the '96 318, it is on the rear of the block, to the right (passenger side) of the distributor. I would assume it would be in the same place, however.
If parts ain't flyin', you ain't tryin'.
