hi paul,
on my dads mig, we have the pipe preasure tap right on the apex of the front, when we bought it from denise last year at fresno, he showed us the location and we did it right there and flew it .
I too don't like pitot psi for the same reason as above, on my two FA18 singles, I could never get the engine to run rich enough, I even tried a radical aproach, installing TWO pitots in the fan and routing one to each main tank, ( did'nt work eather )
the bigest problem, ( the only two problems ) we are having with the weston pipe is, it has a healthy apitite for header orings, easy to change, so not a problem, the other is the high level of vibration in that area, loosens the preasure tap, so we have it jbwelded, and keep an eye on it .
having said that, throw that baby on your jet, youl love it, the needle is not overly sensitive as has been said of mini pipes and in fact, gives the eng. a fairly broad power range, you will want to set the idle mixture fairly lean to get a reliable idle, ( typical byron set up ) and that should do it .
