[DeTomaso] Mech vs electric oil pressure gauges

[Tomas Gunnarsson]

The difference in response time is not an issue unless you're literally staring at the gauge waiting for it to change. For that you use an "idiot light". I personally wouldn't want a pressurized oil line inside my cabin considering how often I rattle things around underneath the dash for various reasons. Reliability? Have you compared mechanical tire pressure gauges as found at gas stations? Let's just say that I carry my own gauge and use the station gauge as a rough guide. The prices you quote are the opposite to what I'd have expected. I'd have thought that an electrical and a mechanical instrument of similar accuracy and reliability would have cost me significantly more for the mechanical than the electric.

> Has anyone looked at the advantage/disadvantages of mechanical versus electric oil pressure gauges?  The gauge I want is like $180 electric and $40 mechanical.  Not an insignificant difference.  I'd guess the response time is quicker for the electric, but in seconds or in milli seconds?  I'd guess the mechanical is more reliable.
