Theres is no reason to use a banjo bolt....he can screw a mechanical guage right into the filter cover.

for ease of set-up he sure can; but i think earp is trying to say for the absolutely most accurate fuel reading a banjo with a mechanical gauge right at the cp3; but then again fluid dynamics anywhere past the filter should have the same pressure

Ok so I have gotten the pressure gauge to work but I understand now that I need a lower pressure gauge. Any one have a part number of a 0-30 PSI setup? I am looking for a auto meter white faced gauge with silver ring if I can. Thank you for any help you all could provide.
