I now have it working great!
I am not sure how to attach the image I have. If you send me your email, I can email it to you.
This is the part I used:
http://www.ebay.com/itm/Engine-Oil-Pressure-Sender-With-Gauge-Standard-PS-261-/180825926259?pt=Motors_Car_Truck_Parts_Accessories&hash=item2a1a10aa73&vxp=mtrI had to remove the starter mount bar and oil filter to replace it.
It is bigger than the Capri sender, but with some work it does fit but very tightly. It did get bent a little on the top when I tightened the starter mount bar.
I found that if the starter mount bar pressed to hard against it, it caused the gauge to pin. To resolve the problem, I put a washer between the back of the starter mount bar and the engine around the bolt(s) that hold it on the bottom. The bolt is shown with the red arrow in my picture. I did strip the other bolt at the bottom, and will need another one if someone has an extra part. I learned how to install the starter mount bar to get it in with the bigger sender:
1. First put in the bottom bolts, with a washer between the mount and engine to make room for the sender, but only screw them in a little. The red arrow shows this.
2. Put the top bolts in, and tighten them. The orange arrows show this.
3. Tighten the bottom bolts. The red arrow.
4. Put in and tighten the starter bolt. The green arrow.
The sender is shown by the white arrow. If you look closely, the wire comes out pointing towards the top-right to avoid shorting against the starter mount bar.
Changes I made to it are:
1. I moved the rubber on the sender up to cover the connector so that it does not short against the starter mount bar.
2. After tightening it, I turned the connector so the wire connects from the top-right to avoid the starter mount bar.
The picture shows that it gives a little higher reading than then old sender, but it looks good. I show both what it looks like when driving and idling.
