Oil pressure sending unit location?

[xtrmjoe]

When I got truck it had newer 350 4 bolt main crate eng. But oil pressure guage never worked. I bought all new digital gages and cant find anything on the eng that resembles the sender. Where do I install the oil pres sending unit. /forums/images/graemlins/1zhelp.gif

the sender is just to the right the distributor looking at it from the front.

It is plumbed on the top left of the block, right behind the intake manifold.

Theres one above the oil filter also.

And on some there is one at the front of the block behind and above the water pump.

The front and rear ones are the same, 1/8" I think, the one on mine above the oil filter is 1/4".
