So I have a distribution block on my engine. A grease gun hose goes from the standard top opening to this block. The block has a large hole and a small hole. The small hole has the standard idiot sensor. This works fine as the light goes off in the dash. A 911 sender is screwed into the large hole. I have a wire going to the gauge in my dash. If I ground the wire to the engine, the gauge pegs at 5 bar/above. The sender is a 0-5bar, the gauge is a 5 bar. What am I missing here? I have even swapped the sender and still I am not getting a reading.

I thought about that as well. I believe the distro block is made from aluminum or stainless steel. That block is bolted to the engine sheet metal. I even added an extra wire to the outside of the sender to test continuity. Maybe I still have a continuity issue.
