Query: Stick to mechanical for oil pressure

Sorry Sunpro, I just left an awesome review for you mechanical gauge, but I have a mechanical gauge because I tried this one first. It bounced all over the place. I don't know if it was the sender or the gauge. I tried several different manifolds (to add or substract fluid damping) which didn't work. I thought maybe it was some king of electrical disturbance so I used different wires and used a shielding sleeve to shield it from electromagnetic disturbances. Nothing worked and the readings kept bouncing. I made sure the manifold was clear and the sender opening was clean... Needless to say I went mechanical, I do use your electrical oil temp gauge which works perfect.
