I had the exact same problem become present on my 305, Q Jet Camaro, it was a faulty pressure regulator at the carburetor.

Re: Question on loosing fuel pressure going down track.
A friend had this same problem this year and found it to be a very restricted fitting from tank to pump. This was after he changed pump and regulator. It was a 90 degree fitting.

Re: Question on loosing fuel pressure going down track.
Is this a stock fuel tank? Not a fuel Cel?
To eliminate a weak (low volume) pump, I would add 5 gallons of fuel. If that stops the pressure drop, it will usually indicate the pump pick up being uncovered due to placement in the tank.

Re: Question on loosing fuel pressure going down track.
It is a fuel cell with about 10 gallons in it mostly to make weight. Has rear sump and exit with pump directly behind it. Im pretty sure I 45 degree or straight fitted everything. I did install a -8 inline fuel filter when I built car 35 passes ago.

It's the G force causing the problem.

Re: Question on loosing fuel pressure going down track.
If you are using a fuel filter, check the Microns.
