best engine bay place for a fuel pressure gauge

I always have the regulator on the passenger inner fender, with a pair of braided lines to the bowls, so i can get the bowls off for a jet change easily. On one car, with a 140 gallon pump, i have a gauge on the fuel bowl (inlet on the pass side, gauge on the driver side) for under the hood monitoring, and an isolator with a gauge inside the car, for monitoring down track.
The other car has a gauge on the regulator, for under hood, and a 250gph mallory that i dont have to monitor in the car.
If i were doing it over, i might try to mount the regulator forward in the car ahead of the carb, so g-forces help feed the carb, instead of stopping fuel flow.
