what kind of manual guage can we use?

 

Just a heads up for everyone running a guage. I had a guage mounted next to the ignition on the dash. Well I had a "little incident with a tree" and broke something inside the gauge. It went unnoticed for a couple miles until I looked down and saw oil everywhere. I had to be towed back. Now I use the oil pressure switch again just to be safe. The funny part is that I put my old "bad switch" back in and the light went out.
