Correct me if I'm wrong, but if you increase the volume wouldn't that naturally increase the pressure because the oil passages and holes are stll the same size. And can anyone tell me which sending unit is for the gauge and which one is for the idiot light. I disconnected both the wires for the two below the filter, the single wire to the big round diaphram type sender and the 3 pin plug to the smaller black one just off to the side of it. Neither one caused the idiot light to come one. The gauge not working at all now and I'm sure it's not a bad connection, I checked both connections so it must be the gauge or the sending unit. I suppose it could be a wire in the wiring harness, all the wires on the drivers side that go to the the three sending units below the power steering pump are in pretty bad shape, I thought I had them repaired well enought to work, it's certainly not an obvious problem with the wires. Any information or ideas on this would be greatly appreciated. I've also still got the starter drilling jug for the 3.4 if anyone is intrested in buying it. Thanks
