Hey Tom, Looking good! Nothing that a few good Toyota parts won't fix.... :eek: Jeff

Yeah, this is my first post, so I figured why not jump right in here. I'm not sure about the fascination with mechanical gauges, especially with all the risk that the mechanical oil pressure gauge carries with it. If mechanical gauges are all that, why don't you use a mechanical temperature gauge? Here's a link to some information from one of the gauge manufacturers. http://www.classicinstruments.com/index.aspx?documentID=mechanicalvselect1 As far as the concept of line size affecting the response of a mechanical gauge I will pose that the amount of trapped air in the line will have a much greater impact on the responsiveness compared to the normal sized line used. If all the air is removed from the system, then the actual amount of fluid Flow approaches zero. How flexible the line is will play a part too. Image a line that was a real soft rubber like material. It would slow down the response because it's volume would change as the pressure changed. It's known as an accumulator or buffer. Anyways, no matter what your opinion is, it's still fun working on your rides, no matter what they are! :) Have Fun, Jeff
