I notice on different forums in the internet that the fuel pressures run 15# idling and around 10 cruising..

Where do most hook up the gauge, to the inlet or exit of the filter?

I installed mine a few days ago and it reads:
14.5# with lift pump running and engine down
10# with engine idling and
8-10# cruising at 70 mph.

I have my FP gauge hooked to the exit side of the filter.

 

post filter is the usual location.....allows you to monitor fuel filter health as well.

Your numbers look good to me....
