Don the bell shaped sender is definitely the wrong one for a light. It actually creates a ground for the gauge when the pressure builds up and will turn the light on instead of off. The one you want is like the one pictured on eBay # 370327121097. As far as I know it doesn't matter what engine you have, they all took the same sender.

One is just off ebay, clearly represented as an "oil light sender". The other two I have were off a 67 440 and a 64 413. I have seen the much smaller sender Dan may be referring toon a 64 225 slant six I had. Is that also correct for a big block idiot light?You guys may have solved this one!!!Thanks, Don ---- Please address private mail -- mail of interest to only one person -- directly to that person.
