For all the time, money, weight and complexity to fit venturi's, vacuum pumps etc. (not to mention endless posts!) Don't you think it would be less of all to step into the 21st century and take advantage of one of the many EFIS's now on the market? All in all they are more reliable, offer better information at a glance (with a little training) and in the long run less expensive.
