    Adding a electric oil p sender to the back of the block. Can I do away with the stock sender? It appears in the wiring diagram, that the oem sender goes to the computer. If I add the aftermarket sneder, do I need to splice the original wire into it so the computer still sees oil pressure? Bytheway, its a 90 with a 350 TBI.

    Why not use a T , so both components have a sender . There are two oil pressure ports already you could tee from if you count the one above the filter .

    So now I am thinking that I will put the aftermarket sender in the port above the filter. Sound good?

    So where does the dash get itsinfo from, the oil p switch still?

    Its a backup for the fuel pump. Once pressure builds up, it turns on the fuel pump. If the relay goes bad, you can still run the motor. You can do without this switch, as most carb to TBI conversions do, but its worth keeping :) The dash guauge gts its singnal from a sender on the other port.
