I've seen all kinds of stuff for guage placement but where is the best place for LP values and where ,If any, for the IP. Primarily for testing although I am considering permenant mounting.

 

I believe on your fuel filter top there are 2 pipe plugs. The one closest to the motor could be used as a before filter pressure source and the one fartherst...furtherest....closest to the drivers side front tire is after the filter/VP supply pressure source.
