[Big-Foot]

Hi Jerome,
I work on a fair number of both small and big-inch racing engines and have found that anything over 5PSI for street use is not only over-kill, it causes problems in float stability regardless of engine size.
I would probably think about putting a dead-head regulator into your fuel system and turn the pressure down unless you are going to be running a track-day or drag-strip event which is the only time you will be able to tip into any reserve capacity beyond 5PSI. Even then, I would probably stop at 7PSI.

While I am new to this forum, I've been around for quite a while - let me know how I can help.
